Omron K8DT-PZ1CN Three-Phase Voltage, Asymmetry & Phase-Sequence/Phase-Loss Monitoring Relay — 17.5 mm DIN Rail, Over/Under Voltage & Imbalance Protection, SPDT Output, 200-240 VAC

The Omron K8DT-PZ1CN monitoring relay is a compact, high-performance protective device designed to safeguard three-phase electrical systems and equipment against unstable supply conditions. This 17.5 mm DIN-rail mount relay monitors overvoltage, undervoltage, voltage asymmetry, incorrect phase sequence, and phase loss in three-phase, 3-wire systems (200-240 VAC) with a single SPDT (Form C) relay output for alarm or control signaling.

With its slim body and Push-in terminals for rapid wiring, the K8DT-PZ1CN reduces panel space requirements and installation time while providing robust protection for motors, compressors, pumps, and other industrial equipment susceptible to power irregularities. The unit’s broad monitoring range helps detect dangerous conditions early, enabling automated response sequences and minimizing potential system failures.

This relay is ideal for industrial control panels and automation systems where comprehensive three-phase power monitoring is critical for equipment safety and operational reliability.
