Engineered by Rockwell Automation, this relay safeguards equipment against under-voltage, over-voltage, phase loss, phase imbalance, and phase reversal scenarios common in 380–415V AC systems. Self-powered and suitable for 50 to 400 Hz operation, it integrates easily into control panels without the need for auxiliary power supplies. Two SPDT contacts provide reliable signaling for alarms or system shutdowns, while adjustable time delays help prevent nuisance trips from transient faults. The Allen Bradley 813S-V3-400V meets demanding control and protection requirements in critical industrial installations, offering reliable performance, programmable latching or inhibit at set levels, and auto reset features.\n\n\u003ch2\u003eKey Features of Allen Bradley 813S-V3-400V\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMonitors three-phase voltage (380–415V AC range)\u003c\/li\u003e\n  \u003cli\u003eSelf-powered—no external supply needed\u003c\/li\u003e\n  \u003cli\u003eProtects against under-voltage, over-voltage, phase loss, imbalance, and reversal\u003c\/li\u003e\n  \u003cli\u003eAdjustable time delay reduces false alarms\u003c\/li\u003e\n  \u003cli\u003eTwo SPDT contacts for flexible control integration\u003c\/li\u003e\n  \u003cli\u003eAuto reset and programmable latch\/inhibit modes\u003c\/li\u003e\n  \u003cli\u003eMeets IP20 degree of protection, Pollution Degree 3 standard\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable, compact design\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 813S-V3-400V\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eVoltage range: 380–415V AC (three-phase), 50–400 Hz\u003c\/li\u003e\n  \u003cli\u003ePower consumption: 13 VA @ 400V AC, 50 Hz\u003c\/li\u003e\n  \u003cli\u003eContacts: 2 × SPDT, 250V AC rated insulation\u003c\/li\u003e\n  \u003cli\u003eTime delay: 1 s ±0.5 s or 6 s ±0.5 s (power ON); adjustable trip delay\u003c\/li\u003e\n  \u003cli\u003eEnvironmental: IP20 enclosure, Pollution Degree 3\u003c\/li\u003e\n  \u003cli\u003eDimensions: 45 × 80 × 99.5 mm (W × H × D)\u003c\/li\u003e\n  \u003cli\u003eScrew terminal torque: max 0.5 N•m\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nThe Allen Bradley 813S-V3-400V is widely used in industrial power systems where continuous monitoring and reliable protection of three-phase equipment are crucial. Typical applications include motor control centers, pump stations, HVAC systems, conveyors, and automated machinery. Its precise detection of voltage anomalies helps prevent costly damage to motors, drives, and sensitive processes. The relay’s programmable time delays and auto reset make it suitable in environments sensitive to voltage fluctuations, reducing machine downtime and system trips caused by transient events. Facilities managers, OEMs, and panel builders integrate the 813S-V3-400V to maintain operational uptime and ensure system safety, particularly in harsh environments where unplanned interruptions or phase failures can disrupt critical operations.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/how-to-choose-the-right-soft-starter-for-your-motor-application\/\" target=\"_blank\"\u003eHow to Choose the Right Soft Starter for Your Motor Application\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-194e-sy\" target=\"_blank\"\u003eAllen Bradley 194E-SY Disconnect Switch\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1321-3r18-b\" target=\"_blank\"\u003eAllen Bradley 1321-3R18-B Resistor Assembly\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870780932395,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_a004e959-eed1-4e77-97a7-a6185b19e8c4.png?v=1723532225","url":"https:\/\/leadtime.ca\/products\/allen-bradley-813s-v3-400v","provider":"LEADTIME","version":"1.0","type":"link"}
