ABB 1SVR730884R4300

The CM-MPN.43S is a versatile relay designed for three-phase monitoring applications. It operates within a voltage range of 300-500 V AC at frequencies of 50/60/400 Hz, featuring a 2 c/o (SPDT) output rated at 250 V / 4 A.

This relay is capable of monitoring all phase parameters including over/undervoltage, phase unbalance, and phase failure. The threshold values for these parameters are adjustable to suit specific requirements.

The CM-MPN.43S also offers the option to monitor phase sequence and provides automatic phase sequence correction. Additionally, it includes an ON or OFF tripping delay that can be set within a range of instantaneous to 30 seconds (0, 0.1-30 s).

The output contacts can be configured as either 1x2 c/o (SPDT) common signal or 2x1 c/o (SPDT) separate signals for over- and undervoltage thresholds. The tripping delay is adjustable, allowing for a wide range of settings.

For added protection, the device features a sealable transparent cover to prevent unauthorized changes. It also employs screw connection technology with double-chamber cage connection terminals for secure and reliable connections.
