The LWRS series is a phase control relay that monitors three-phase power for correct sequence and loss of any phase, with an LED indicator and a 10 A SPDT relay output. It is a 11-pin plug-in mounted device, weighing 7 oz (200 g). The relay operates from 3 x 220 VAC, 3 x 380 VAC, or 3 x 440 VAC input, with a power consumption of 3 VA at 220 V. Contacts are AgCdO, rated for 250 VAC/DC switching voltage and 2200 VA resistive load. Electrical life is 2 × 10⁵ operations at full load, and mechanical life is 30 × 10⁶ operations. Operating temperature ranges from -10°C to +60°C. The device is UL listed and CSA recognized.
