Omron K8DT-PH1CN Phase-Sequence & Phase-Loss Monitoring Relay — 17.5 mm DIN Rail, SPDT Output, 200-480 VAC, 3-Phase Protection (Sequence & Loss)

The Omron K8DT-PH1CN is a slim, high-performance phase-sequence and phase-loss monitoring relay designed to protect three-phase equipment such as motors, compressors, and industrial drives from damage due to incorrect phase order or loss of phase. With its compact 17.5 mm DIN-rail package and SPDT (1 Form C) relay output, it offers reliable protective monitoring for three-phase, three-wire systems operating on 200 – 480 VAC supplies.

This relay continuously checks the sequence and presence of phases and triggers its output contact if an abnormal condition is detected, helping prevent reverse rotation, motor stress, and potential equipment failure. Its Push-in Terminal design simplifies installation and reduces wiring time, while the integrated LED indicators allow clear visual status verification. The K8DT-PH1CN is ideal for industrial panels and control systems requiring dependable voltage stability protection, and it meets global performance standards for automation safety.
