The 1SVR730774R1300: This monitor sits between the supply and the motor contactor, watching for phase loss, phase sequence reversal, and undervoltage on three-phase systems. When a fault is detected, its internal relay drops out, opening the contactor coil circuit and protecting the load. The CM-PAS.31S is a common choice for pump stations, conveyors, and HVAC compressor banks where an unmonitored phase loss can burn out a winding in seconds.
