CM-MPS.21S Three-phase monitoring relay 2c/o, 0,0.1-30s, L1-L2-L3-N=3x180-280VAC

CM-MPS.21S Three-phase monitoring relay 2c/o, 0,0.1-30s, L1-L2-L3-N=3x180-280VAC

Item Code: 1SVR730885R3300

The CM-MPS.21S is multifunctional relay from the CM three-phase monitor range. It operates with rated control supply voltage / three-phase measuring voltage of 180-280 V AC 50/60Hz and has a 2 c/o (SPDT) output with contacts rated at 250 V/ 4A. This relay is also suitable to monitor single-phase mains. It monitors alll 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 ON or OFF tripping delay are selectable. The tripping delay is adjustable over a range of instantaneous to 30s (0, 0.1-30s). A sealable transparent cover for protection against unauthorised changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.
