Why Choose the ABB CM-MPS.23P Three-Phase Monitoring Relay?
The ABB CM-MPS.23P is a multifunctional three-phase monitoring relay designed to monitor critical electrical parameters in AC power systems. As part of the ABB CM-MPS three-phase monitoring relay series, it provides monitoring for phase failure, phase sequence, overvoltage, undervoltage, phase unbalance and interrupted neutral conditions.
The relay continuously monitors the connected electrical supply and provides a switching response when configured voltage or phase conditions are exceeded. Adjustable threshold values, automatic phase sequence correction and selectable phase sequence monitoring allow the CM-MPS.23P to be configured for a range of industrial control and protection applications.
With a rated control supply and three-phase measuring voltage of 3 × 180–280 V AC and a broad 45–440 Hz operating frequency range, the CM-MPS.23P provides a compact monitoring solution for three-phase electrical systems. Its maintenance-free Easy Connect Technology with push-in terminals enables straightforward installation on DIN rails within industrial control panels and automation systems.

Reliable Three-Phase Monitoring for Industrial Control Systems
Three-phase monitoring relays such as the ABB CM-MPS.23P help protect electrical equipment and control systems by continuously checking important supply parameters. Detecting phase failure, incorrect phase sequence, voltage deviations and phase unbalance can help identify abnormal operating conditions before they affect connected equipment.
The CM-MPS.23P combines several monitoring functions within a single compact device. Adjustable voltage and phase unbalance thresholds, configurable automatic phase sequence correction and selectable tripping delays allow the relay to be adapted to different industrial control requirements. Its configurable relay contacts can provide a common signal or separate signalling for overvoltage and undervoltage thresholds.
