What is the ABB CM-MPS.41 Multifunction 3-Phase Monitoring Relay?
ABB CM-MPS.41 is a very reliable, 3-phase multifunctional monitoring relay, which offers excellent protection against voltage-related faults to motors, machines, and other sensitive equipment. On a 24V AC/DC control supply, this relay monitors the following essential electrical parameters: phase sequence, phase presence, over/under voltage, and phase unbalance.
The relay allows this in industrial and marine automation environments—where system downtime is prohibitively expensive and human safety is critical—the continuous, steady, and highly accurate monitoring of your 3-phase power supply.
It is normally installed in control panels, motor control centers, generator systems, and automation equipment to prevent premature equipment failures due to unstable power conditions.
Key Features of ABB CM-MPS.41 Multifunction Monitoring Relay
