The CM-MPN.72P is a multi-functional relay from the CM three phase monitors range. It operates with a rated control supply voltage/three-phase measuring voltage of 530 to 820 VAC 50/60 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 VAC/4 A. This relay monitors all phase parameters such as over/undervoltage, phase unbalance and phase failure. The corresponding threshold values are adjustable. The CM-MPN.72P also offers selection of phase sequence monitoring, automatic phase sequence correction as well as an ON or OFF tripping delay. The output contacts can be configured as 1x2 c/o (SPDT) contacts (common signal) or 2x1 c/o (SPDT) contact (separate signal for over and undervoltage thresholds) operation. The tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1 to 30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers maintenance free easy Connect technology with push-in terminals.
