ABB Group 1SVR430885R1300 CM-MPS Monitoring Relay

ABB CM-MPS Monitoring Relay, model 1SVR430885R1300, is a component of ABB’s CM-MPS family of multifunctional three-phase monitoring relays designed for electrical distribution panels. This device performs real-time supervision of essential supply conditions in three-phase networks and provides a controlled output signal to trigger upstream protection when thresholds are exceeded. As part of the CM-MPS line, it is offered in variants with different terminal configurations (screw or push-in) and with or without neutral monitoring, enabling flexible wiring to suit various installation practices and voltage schemes. The CM-MPS family is known for compact panel mounting, straightforward wiring, and configurable parameters that address common three-phase monitoring needs such as voltage presence, phase sequence, and fault signaling, helping prevent unscheduled outages and equipment damage. This particular model, identified by the 1SVR430885R1300 ordering code, aligns with ABB’s cataloged CM-MPS devices used by electrical engineers and integrators to safeguard motors, transformers, and motor control centers in industrial and commercial power systems.
