ABB 1SVR760488R8300

The CM-MPN.62S is a versatile relay within the CM three-phase monitor series. It operates with a rated control supply voltage / three-phase measuring voltage of 450-720 V AC 50/60 Hz and features a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. This relay is designed to monitor all phase parameters such as over/undervoltage, phase unbalance, and phase failure. The corresponding threshold values are adjustable. The CM-MPN.62S 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 an accessory. The device features maintenance-free Easy Connect Technology with push-in terminals.
