Schneider Electric LP1K0610BD Contactor, TeSys K, 3P, AC-3, Rated ≤ 440V, 6A, 1 NO Auxiliary Contact, 24VDC Coil — Specs, Price, and Review Guide

Controls engineers and maintenance technicians searching for the Schneider Electric LP1K0610BD are typically at one of two moments: verifying this is the correct replacement before placing an urgent order, or confirming the spec fits a new panel build before committing the BOM. This compact three-pole TeSys K contactor is rated 6A AC-3 at ≤ 440VAC with a fixed 24VDC coil, measures 45 mm wide by 57 mm deep by 58 mm high, and carries UL, CSA, IEC 60947, and VDE 0660 certifications — making it a globally deployable component for small motor control in tight panel spaces.

Who Should Buy the LP1K0610BD — and Who Should Not

The LP1K0610BD is the right choice for engineers and technicians who can check all of the following boxes before ordering:

  • Your control circuit operates at exactly 24VDC — this model has a fixed coil voltage and cannot be adapted to 120VAC or 230VAC
  • Your motor or load draws no more than 6A AC-3 at ≤ 440VAC — the motor power rating is 3 kW at 440VAC, 50/60 Hz
  • You need three-pole normally open main contacts — the LP1K0610BD is 3PST-NO and cannot be reconfigured
  • One normally open auxiliary contact is sufficient for your feedback or signaling circuit
  • Your panel installation requires DIN-rail or surface mount at 45 mm width
  • Your project requires UL, CSA, IEC, and/or VDE certification — all are covered on this SKU

If your motor load exceeds 6A at 440VAC, step up to the LP1K1010BD (10A) or LP1K1610BD (16A). If your control circuit is 120VAC or 230VAC, this is the wrong part — order the correct coil voltage variant from the LP1K family instead.

What the LP1K0610BD Actually Does in a Control System

The Schneider Electric LP1K0610BD is an electromechanical contactor — it is the remotely controlled electrical switch that sits between your PLC output or relay logic and the motor or load you need to turn on and off. When the 24VDC coil receives its control signal, it energizes an electromagnet that physically closes the three main poles, completing the three-phase circuit to the motor. When the signal drops, internal springs return the contacts to their open (off) state. The 1 NO auxiliary contact provides a simultaneous feedback signal — typically wired back to a PLC digital input to confirm that the contactor actually closed.

The TeSys K family occupies the compact end of the contactor market. At 45 × 57 × 58 mm and approximately 230 g, the LP1K0610BD is physically smaller than the next product tier up (TeSys D), which matters significantly in densely packed control cabinets or portable equipment enclosures. The 3 W coil power consumption is low enough that a standard 24VDC PLC output module can drive the coil directly without an intermediate relay on most systems — though always verify your PLC output current rating against the coil requirements before assuming this.

Electrical endurance on the LP1K0610BD exceeds 100,000 operating cycles per IEC 60947-4-1, and the contactor is rated for up to 3,600 switching cycles per hour. In a typical industrial duty cycle running 10 operations per day, that endurance translates to a very long service life before contact wear becomes a maintenance concern.

Typical System Architecture for the LP1K0610BD

The LP1K0610BD sits in the switching layer between the control signal source and the motor load. Here is where it fits in a standard motor control circuit:

  • PLC or relay controller outputs a 24VDC signal to the contactor coil terminals (A1/A2)
  • LP1K0610BD coil energizes, closing the three main poles and the 1 NO auxiliary contact simultaneously
  • Three-phase power (L1, L2, L3) feeds through the main poles to the motor terminals
  • The auxiliary NO contact feeds back to a PLC digital input, confirming contactor status in the control logic
  • Downstream motor overload relay (if fitted) is wired in series between the contactor load terminals and the motor to provide thermal protection

Where the LP1K0610BD Gets Specified: Industries and Applications

The LP1K0610BD covers the most common small motor control scenario in industrial automation: a three-phase motor rated at or below 3 kW at 440VAC, controlled by a 24VDC PLC or relay logic system in a panel where space is constrained. Conveyor drives, small pump stations, and fan control in HVAC systems are textbook applications — the 6A AC-3 rating handles the motor inrush that comes with direct-on-line starts in these applications.

In packaging machinery and material handling systems, the TeSys K contactor often appears in multiples — a dozen or more units mounted on a single DIN rail to control individual conveyor zones or actuator circuits. The 45 mm width means more contactors fit per metre of DIN rail compared to larger form factors, which directly reduces enclosure footprint and panel build cost.

OEM machine builders standardizing on the TeSys K family specify the LP1K0610BD as the base motor control component across product lines. Multi-standard certification — UL NLDX2, CSA File No. E164862, IEC 60947, CE, VDE 0106 and VDE 0660 — means the same part number ships in equipment destined for North American and European customers without requiring region-specific variants, which simplifies spare parts inventory management significantly.

In food and beverage and textile production environments, the LP1K0610BD handles smaller process motors — mixers, conveyors, winders — where the 6A load and 24VDC control voltage match the standard control architecture of most modern PLCs in these sectors. Marine vessel motor control is a secondary use case where the compact size and robust certification profile are both relevant.

LP1K0610BD vs. LP1K1010BD vs. LP1K1610BD: Which Variant Do You Need?

Model Rated Current (AC-3) Coil Voltage Auxiliary Contact Key Differentiator
LP1K0610BD (This Model) 6A at ≤ 440VAC 24VDC 1 NO Smallest form factor; lowest cost entry point
LP1K1010BD 10A at ≤ 440VAC 24VDC 1 NO Next step up for motors drawing 7–10A
LP1K1610BD 16A at ≤ 440VAC 24VDC 1 NO Covers motors up to approximately 7.5 kW at 440VAC
LP1K2510BD 25A at ≤ 440VAC 24VDC 1 NO Upper range of TeSys K; larger loads
LP1K series (other coil voltages) 6A–25A 12VDC, 48VDC, 120VAC, 230VAC 1 NO Same family; different coil suffix in part number

If your motor nameplate shows a full load current above 6A at 440VAC, the LP1K0610BD is not the correct choice regardless of cost — check current availability of LP1K series variants at LeadTime.ca and confirm the right current rating before ordering.

Expert Verdict: Is the LP1K0610BD Worth Ordering?

The LP1K0610BD earns its place as the standard compact contactor for small three-phase motor control. It is specifically right for plant maintenance technicians managing motors at or below 3 kW at 440VAC, automation integrators building cost-conscious panels where 24VDC control infrastructure is already in place, and OEM machine builders who need a single TeSys K SKU that clears UL, CSA, IEC, and CE requirements simultaneously. The 45 mm width and 230 g weight are genuine advantages — not marketing language — in panel designs where every millimetre of DIN rail counts. The multi-standard certification across UL NLDX2, CSA File No. E164862, IEC 60947, and VDE 0660 means a procurement team can standardize on this part number for shipments across North America and Europe without maintaining separate regional variants.

Where the LP1K0610BD has real limits: the IP2X enclosure rating rules it out for washdown, outdoor, or coastal spray environments — those applications need IP55 or higher. The −25 to +50 °C operating range covers standard industrial conditions but excludes extreme environments at both ends. And the fixed 24VDC coil is a hard boundary — if your facility runs 120VAC or 230VAC control circuits, this model simply will not work. For loads above 6A at 440VAC, the LP1K1010BD (10A) or LP1K1610BD (16A) are the correct next steps within the same product family. For resistive or non-inductive loads (AC-1 applications), a dedicated AC-1 rated contactor is more appropriate than forcing an AC-3 device into that role.

From a procurement standpoint, the LP1K0610BD is one of the better-stocked compact contactors in the North American distribution network — most authorized distributors carry it with 1 to 3 business day lead times, and it ships worldwide through specialist industrial distributors. Ordering through a specialist channel rather than a generic marketplace matters here: you get access to current datasheet revisions, technical pre-sales support, and warranty coverage that generic listings cannot guarantee.

What Engineers Need to Know Before Ordering the LP1K0610BD

Because forum-level discussion specifically around the LP1K0610BD is limited compared to higher-volume PLC modules, the most reliable guidance on ordering this contactor comes from the technical specification itself and the pattern of mistakes that specialist distributors and Schneider Electric support teams see repeatedly. The three most consequential errors are coil voltage mismatch, load current undersizing, and auxiliary contact count confusion — and all three share the same root cause: the buyer did not cross-check the part number suffix against their actual system requirements before ordering.

The coil voltage issue is the most common. The LP1K series encodes coil voltage in the part number suffix: BD denotes 24VDC. Other suffixes in the same family cover 12VDC, 48VDC, 120VAC, and 230VAC. A technician pulling a replacement from a panel label or maintenance record who transcribes the wrong suffix ends up with a contactor that will not energize on the existing control circuit. The fix costs nothing if caught before ordering — it costs a project delay and a re-order fee if caught after the part arrives on site. Measure the coil voltage with a multimeter at the existing contactor terminals if there is any uncertainty at all.

The load current issue is more nuanced. The 6A AC-3 rating already accounts for motor inrush at startup under AC-3 duty — but it does not leave margin for a motor that is running at or near its nameplate FLA continuously in a warm enclosure. Engineers specifying this contactor for a motor drawing 5.5–6A should seriously consider stepping to the LP1K1010BD (10A) to preserve thermal margin, especially in enclosures operating near the +50 °C upper limit. Undersized contactors in thermal stress fail without warning and at the worst possible time. The auxiliary contact situation is simpler: this SKU provides exactly 1 NO. If the control logic requires a normally closed contact or a second auxiliary output, a different LP1K variant or TeSys D model is necessary — there is no field modification available on this part.

Wiring and Installation Overview for the LP1K0610BD

  • Connect 24VDC positive to coil terminal A1 and negative to A2 using screw-clamp terminals rated for the wire gauge in use; terminal capacity on this model is 0.5–1.5 mm² — do not use undersized wire on main load contacts
  • Main three-phase supply connects to terminals L1, L3, and L5 (incoming); motor leads connect to T1, T3, and T5 (outgoing) — verify terminal labeling against the current revision of the Schneider Electric installation guide before wiring
  • The 1 NO auxiliary contact provides a status feedback signal; wire it to a PLC digital input or indicator circuit to confirm contactor energization in the control logic
  • Always de-energize and lock out both the control circuit (24VDC) and the main power circuit (three-phase) before installation, maintenance, or terminal inspection — IP2X provides basic finger protection but does not substitute for lock-out/tag-out procedure
  • DIN-rail mounting is the standard installation method; verify that 45 mm of width and the full depth of 57 mm are available in the enclosure before mechanical assembly

Compatible Accessories and System Expansion

The LP1K0610BD is part of the TeSys K family, which supports accessory mounting for additional auxiliary contact blocks and surge suppression modules. Confirm accessory compatibility with the current Schneider Electric TeSys K product catalog before specifying add-on components, as accessory availability varies by current rating tier within the family. Common system components used alongside the LP1K0610BD include:

  • TeSys K auxiliary contact blocks — adds additional NO or NC contacts where 1 NO is insufficient for the control logic
  • Surge suppression modules — RC network or varistor type; recommended when switching inductive loads to protect the 24VDC control circuit from voltage spikes at coil de-energization
  • Motor overload relays (TeSys series) — thermal or electronic type; wired in series with LP1K0610BD load terminals to provide motor thermal protection; required by most electrical codes when the contactor is used as a motor starter
  • 24VDC power supplies — DIN-rail mounted SMPS supplying the control circuit; must be sized to reliably deliver coil current for all contactors in the panel simultaneously

Wrong-Part Prevention Checklist

Before finalizing any order for the LP1K0610BD, confirm each of the following against your actual system requirements:

  1. Verify coil voltage: this model is 24VDC only. Do NOT order if your control circuit is 120VAC or 230VAC. Check your PLC or relay coil voltage before confirming.
  2. Confirm load current: at 440VAC (AC-3), this contactor is rated 6A. If your motor or load draws more than 6A, order a higher-rated variant (10A, 16A, etc.).
  3. Check auxiliary contact count: this SKU includes 1 NO contact. If you need 2 contacts or a NO+NC combination, specify the correct model variant.
  4. Ensure DIN-rail availability: while this model supports DIN-rail mount, verify your panel space allows 57 mm width.
  5. Confirm contact configuration: this is 3-pole only (three-phase motor control). For single-phase or two-phase applications, confirm suitability with the control system designer.
  6. Check standards compliance: verify UL, CSA, IEC, and VDE approvals match your regional requirements and facility certification needs.

If any item on this checklist surfaces a mismatch, contact the LeadTime.ca team before ordering — we can confirm the correct LP1K variant or identify the right alternative for your application.

Frequently Asked Questions

Can I use the LP1K0610BD to control a single-phase motor instead of a three-phase motor?

The LP1K0610BD has three main poles configured for three-phase use. Using it on a single-phase load is technically possible in some configurations, but it is not the intended application and may not comply with your electrical code or facility certification requirements. Confirm suitability with your control system designer and consult Schneider Electric application guidance before proceeding.

What happens if the load current slightly exceeds the 6A AC-3 rating — will it trip or fail silently?

Electromechanical contactors do not have built-in overload trip mechanisms — that function belongs to a separate motor overload relay wired in series. A contactor running above its rated current will experience accelerated contact wear and thermal stress, eventually leading to contact welding or premature failure without a clear warning event. Always pair the LP1K0610BD with an appropriately sized motor overload relay, and do not operate it continuously above the 6A AC-3 rating.

Is the LP1K0610BD a direct replacement for an older TeSys K contactor with the same current and coil ratings?

In most cases, yes — the TeSys K family has maintained consistent terminal layouts and footprint across generations, making the LP1K0610BD a straightforward retrofit into existing TeSys K installations with matching coil voltage and current rating. However, always verify the terminal labeling and mounting dimensions against your existing installation before assuming a direct swap, particularly if the installed unit is an early-generation TeSys K.

What does the AC-3 utilization category mean, and does it apply to fan and pump loads?

AC-3 is the IEC utilization category for squirrel-cage induction motors with direct-on-line starting — the contactor closes against locked-rotor inrush and opens at full running current. Fan and pump loads driven by squirrel-cage induction motors fall squarely within AC-3 duty. Resistive loads such as heating elements fall under AC-1, which has different rating criteria. Using an AC-3 rated contactor on resistive loads is generally acceptable, but verify with the LP1K datasheet for the specific application.

Can the LP1K0610BD coil be driven directly from a standard PLC transistor output?

The 24VDC coil consumes 3 W. Most modern 24VDC transistor PLC output modules can drive this load directly, but you must verify that the output module's current rating per channel exceeds the coil's inrush and steady-state current requirements. Consult both the LP1K0610BD datasheet and your PLC output module specifications before wiring directly — if margin is tight, an interposing relay is the conservative approach.

Is the LP1K0610BD suitable for outdoor or washdown environments?

No. The LP1K0610BD carries an IP2X enclosure rating, which provides protection against finger contact with live parts but not against water ingress, dust, or spray. For outdoor, washdown, or high-humidity environments, a contactor rated IP55 or higher is required. The operating temperature range of −25 to +50 °C also excludes extreme outdoor temperature conditions in some climates.
