ABB CM-MPS.31S THREE-PHASE MONITORING RELAY MEASURING & CONTROL (L-N) 160 -300VAC 2CO

Product Code: CM-MPS.31S

This three-phase monitoring relay is designed to monitor all phase parameters, including over/undervoltage, phase unbalance, phase failure, and interrupted neutral. It has a measuring range of 160 to 300 V AC (L-N) and operates with a rated control supply voltage within the same range. With its 2 CO (SPDT) outputs, it provides reliable control. The double-chamber cage connection terminals ensure secure and efficient wiring.
