The CM-MPS.21S 1SVR730885R3300 is a multifunctional relay in the CM three-phase monitor series. This relay 

is also suitable for monitoring single-phase power supplies. It monitors all phase parameters, such as overvoltage/

undervoltage, phase imbalance, phase failure, and neutral conductor interruption. The corresponding thresholds 

are adjustable. Phase sequence monitoring and an ON or OFF tripping delay are optional. The tripping delay is 

adjustable in the instantaneous range up to 30 seconds (0, 0.1-30 seconds). A sealable transparent cover is available 

as an accessory to prevent unauthorized modifications. The device features screw connection technology with 

dual-chamber retaining terminal blocks.
