Product details

Phase monitoring relay for three-phase systems

The Omron K8DS-PU1 is an active-production phase loss and phase sequence monitoring relay, supplied at 200–240 VAC, with a single SPDT relay output rated 5 A at 250 VAC. Its adjustable delay covers 0.1 to 30 seconds, letting you dial out transient dips that would otherwise nuisance-trip during motor start.

DIN rail mount with SPDT output (1 Form C). Supply 200–240 VAC; delay adjustable 0.1–30 s.
