Crouzet Monitor - Relay Output DWRS440A

The DWRS440A is a phase control relay designed to monitor the phase sequence and detect loss of any phase in three-phase power supplies. It features a single-pole double-throw (SPDT) output relay that is energized when the phase sequence is correct and de-energized when there is a phase loss or reversal. The relay operates on input power ranging from 220 to 440 VAC at 60 Hz, with a power consumption of 3 VA at 220 V. The maximum load capacity is 10 A for AC resistive loads and 1 A for inductive loads, with a maximum switching voltage of 250 VAC and 250 VDC. The relay has a mechanical life of 30 million operations and an electrical life of 200,000 operations at a 2200 VA resistive load. It operates effectively in temperatures ranging from -10¬8C to +60¬8C and weighs 200 grams. The product is suitable for DIN-rail or panel mounting, making it versatile for various applications.
