It detects a missing phase or incorrect phase rotation and drops the SPDT relay output (1 Form C) when the condition is unsafe. Supply range covers 200 to 480 VAC — fits most European and North American three-phase systems without a separate control transformer. The relay contacts are rated 5 A at 250 VAC, enough to directly switch a contactor coil or alarm circuit. No adjustable delay — it trips immediately on fault, which is the right behavior for a safety-critical phase monitor where every cycle counts. DIN-rail mount snaps into any standard 35 mm rail, so panel integration is straightforward.","metaTitle":"Omron K8DT-PH1CN Phase Loss/Sequence Relay, 200-480VAC, SPDT","metaDescription":"Active Omron K8DT-PH1CN phase loss and phase sequence relay. 200-480VAC supply, SPDT relay output, 5A @ 250VAC contact rating.
