ABB 1SVR740885R3300 3-Phase Monitoring Relay, 180 to 280 VAC, 4 A, 2NO-2NC SPDT Contact
The CM-MPS.21P is a multi-functional relay from the CM three phase monitors range. It operates with a rated control supply voltage/three-phase measuring voltage of 180 to 280 VAC 50/60 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 VAC/4 A. This relay is also suitable to monitor single phase mains. It monitors all phase parameters such as over/undervoltage, phase unbalance, phase failure as well as an interrupted neutral. The corresponding threshold values are adjustable. Phase sequence monitoring as well as an ON or OFF tripping delay are selectable. The tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers maintenance free easy Connect technology with push-in terminals.
