Omron K8DT-PZ2CN is a three-phase monitoring relay that detects phase loss and incorrect phase sequence, latching an SPDT relay output rated 5 A at 250 VAC. It runs directly off a 380 to 480 VAC supply — no separate control voltage. The trip delay is adjustable from 0.1 to 30 seconds, enough to ride through motor starting transients or short supply dips. Operating range spans -20 to 60 °C, covering most indoor panel environments. DIN rail mount, box packaging.
