K8DS-PH1 FAZ
Manufacturer: OMRON
Condition: New and Unused, Surplus.
Overview of Omron K8DS-PH1-FAZ
The Omron K8DS-PH1-FAZ is a compact phase-sequence and phase-loss monitoring relay designed for three-phase, three-wire AC power systems. It monitors the phase sequence and detects phase loss to protect equipment from electrical faults. The device features a single SPDT relay output (normally closed operation) with LED indicators for power and relay status and mounts easily on a DIN rail.
