Siemens Residual Current Circuit Breaker SENTRON 5SM2845-8, 63A, 4-Pole, 1000 mA, Type A, 400V AC

Siemens 5SM2845-8 Residual Current Circuit Breaker from the SENTRON 5SM2xxx series is engineered for robust electrical protection in industrial, manufacturing, commercial, and automation environments. It ensures safety by detecting residual currents and quickly disconnecting the power supply to prevent electric shocks and fire hazards.

This device features a current rating of 63 amperes and is designed with 4 poles supporting three-phase power systems. The Type A tripping characteristic allows it to detect both AC and pulsating DC residual currents, providing enhanced protection in modern electrical installations.

The breaker operates at a rated AC voltage of 400V and has a trip sensitivity of 1000 mA, offering reliable leakage detection. It has a short break time to quickly interrupt faulty circuits, minimizing risk.

The unit mounts easily on DIN rails and uses screw terminals for secure and straightforward wiring connections. Measuring 90 mm in height, 124 mm in width, and 77 mm in depth, it fits efficiently within standard electrical panels.

Reset is facilitated by a lever actuator allowing for simple manual resetting after a fault clearance. The device conforms to multiple international standards including EAC, CE, CCC, and VDE, demonstrating compliance with stringent safety and quality regulations.

Produced in the Czech Republic, this residual current circuit breaker combines precision engineering with reliable performance. It is engineered to withstand typical mechanical service life with up to 10,000 switching cycles and an overvoltage category rated at III.
