The DWRA440A is a three-phase phase control relay that monitors phase sequence, loss of any phase, and voltage asymmetry up to 15%, with a SPDT 10 A AgCdO relay output rated for 250 VAC and 250 VDC. It operates from 3 × 440 VAC, 60 Hz power with 3 VA consumption, and has an operating temperature range of -10°C to +60°C. The device features an LED status indicator and a 100 ms off-delay response during phase loss. It is mounted on a DIN rail and weighs 200 g. UL listed and CSA recognized for the 220 VAC version only.
