ABB 3 Phase Monitoring Relay, DPDT Contact Configuration, DIN Rail Mount, 400V AC, 4 VA Power 1SVR730884R4300 CM-MPS.43S

The ABB 1SVR730884R4300 CM-MPS.43S Monitoring Relay is a robust and reliable electrical component for three-phase systems, providing critical protection against power faults such as phase failure, undervoltage, and overvoltage. With its double-pole double-throw (DPDT) contact configuration and DIN rail mounting design, it fits compactly within industrial control panels and electrical enclosures.

Powered directly from the monitored circuit through a 400V AC supply and consuming 4 VA, this relay is highly efficient and suited to rugged environments due to its screw terminal connections, which offer strong resistance to vibration that might otherwise cause connection issues.

Its adjustable time delay feature, ranging from 0 to 30 seconds, enables it to accurately discriminate short-term overloads, preventing unnecessary trips while ensuring electrical system protection. The relay's operational temperature range from -25°C to 60°C makes it suitable for demanding industrial settings including automotive manufacturing, heavy engineering workshops, and bottling plants.

The device is engineered to immediately trigger circuit breakers upon detecting electrical anomalies, thus safeguarding equipment and personnel from damage or hazards. Its dimensions (103.7 mm length x 22.5 mm width x 85.6 mm height) ensure it integrates seamlessly in DIN rail-based assemblies. Compliance with UL standards underscores its quality and reliability.

Adjustable time delay from 0 to 30 seconds for overload management. Screw terminal connections provide strong vibration resistance. Compact form factor for DIN rail mounting standard setups. Wide operating temperature range of -25°C to 60°C for harsh conditions.

UL certified ensuring compliance with international safety standards. Monitors phase failure, undervoltage, and overvoltage faults precisely. Instant circuit breaker tripping function for fault protection. Designed for automotive, heavy engineering, and bottling plant applications.

Easy, tool-free DIN rail installation.
