It operates with a rated control supply voltage \/ three-phase measuring voltage of 350-580 V AC 50\/60 Hz and has a 2 c\/o (SPDT) output with contacts rated at 250 V \/ 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.52S 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, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals."}
