RM22 Harmony Control Relays

Schneider Electric RM22 Harmony Control Relays monitor current, voltage, phase, and three-phase supply conditions in industrial and building control systems. These 22.5mm-wide relays detect conditions such as overcurrent, undercurrent, overvoltage, undervoltage, phase loss, incorrect phase sequence, and phase asymmetry. The relay outputs communicate detected faults, enabling the control system to correct or shut down affected equipment. Schneider Electric RM22 Harmony Control Relays feature front-panel controls protected by an IP50 cover, along with LED status indication and an illuminated dial pointer for setup in low-light environments. Options include a diagnostic button for checking the downstream circuit, adjustable thresholds, time delays, and window monitoring. These relays are designed for mounting on 35mm DIN rails.
