CM-MPS.31S – Multifunctional, 3-phase monitoring 3×160-300V AC The CM-MPS.31S is a multifunctional relay from the CM three-phase monitors range. It operates with a rated control supply voltage / three-phase measuring voltage of 160-300 V AC 50/60 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. This relay monitors all phase parameters such as over/undervoltage, phase unbalance and phase failure. 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 screw connection technology with double-chamber cage connection terminals.
1SVR730884R1300 – CM-MPS.31S Three-phase monitoring relay ABB 3-Phase Monitoring Relays is a genuine ABB electrical component designed for industrial automation, motor control, and power distribution applications.
ABB products are widely used across commercial and industrial installations where reliability, safety, and long operational life are required.
