Checking for live stock

The ABB CM-MPS.41S (1SVR730884R3300) is a robust three-phase monitoring relay designed to guard electrical systems from under- or overvoltage, phase loss, phase imbalance, or incorrect phase sequence. With a narrow 22.5 mm DIN-rail footprint and a wide sensing range (300–500 V AC, 45–65 Hz), it offers reliable protection in compact industrial installations. Its configurable time delays (0.1–30 s) and DPDT contacts make it ideal for integrating into control systems and safety circuits in motors, panels, and automation setups.

Why Professionals Trust the ABB CM-MPS.41S Monitoring Relay?

Engineers and system integrators rely on the CM-MPS.41S monitoring relay for its precise voltage and phase monitoring and fast reaction to anomalies. It is known for its reliable dual changeover (DPDT) outputs and UL-certified compliance that ensures secure, fail-safe operation under challenging conditions (–25 °C to +60 °C).
