The Schneider Electric Harmony RM22TA33 is a self-powered 3-phase control relay that continuously monitors phase sequence, phase loss and phase asymmetry on three-phase supplies from 380 V to 480 V AC. Two change-over relay outputs (5 A/250 V AC, 2000 VA) provide reliable signalling or control, while an adjustable fault time delay (0.1…30 s) and fixed 2 % hysteresis help prevent nuisance tripping. Compact 22.5 mm DIN-rail housing, front-panel LEDs and a built-in test button make installation and diagnostics fast and intuitive.
