Crouzet Monitor - Relay Output LWRA380A

The LWRA380A is a three-phase phase control relay designed to monitor phase sequence and detect loss of any phase, even at 95% of nominal voltage. It features an SPDT 10 A AgCdO relay output with a 250 VAC/250 VDC switching rating and 220 VA power rating. The device operates directly from 3 x 380 VAC, 60 Hz input with 3 VA power consumption. It includes an LED status indicator and a top-mounted potentiometer adjustable for phase asymmetry between 5% and 15%. The relay has a mechanical life of 30 x 10^6 operations and an electrical life of 2 x 10^5 operations at 220 VA resistive load. It operates from -10°C to +60°C and weighs 200 g. The unit is mounted via an 11-pin plug-in connector.
