Siemens SENTRON Residual Current Circuit Breaker 100A, 4-Pole, 1000mA Trip Sensitivity, Type A, 400V AC 5SM2847-8

Siemens 5SM2847-8 Residual Current Circuit Breaker (RCCB) is a high-performance electrical safety device from the SENTRON 5SM2xxx series designed for industrial and commercial applications requiring reliable earth fault protection. Rated at 100A with 4 poles, this RCCB operates at 400V AC and features a trip sensitivity of 1000mA to provide fast and effective detection of residual currents.

The Type A tripping characteristic enables the breaker to detect both AC and pulsating DC residual currents, thus catering to versatile electrical installations. Its compact design with dimensions 124mm width, 90mm height, and 70mm depth facilitates easy DIN rail mounting, optimizing space in electrical panels.

The device includes screw terminal connections ensuring robustness in electrical contacts, and a lever-type reset actuator allows quick manual reset after fault clearance. Its short break time ensures rapid interruption of fault current, safeguarding equipment and personnel.

Manufactured in the Czech Republic, this circuit breaker complies with international standards including EAC, VDE, CE, and CCC certification marks, guaranteeing quality and conformity with safety norms.

Typical applications include industrial electrical distribution, commercial building installations, automation systems, and safety-critical environments where rapid response to earth leakage currents is vital.

This breaker has a current rating of 100A, suitable for medium to high-capacity circuits. Incorporates 4 poles for switching all phases plus neutral in 3-phase systems. Type A tripping characteristic detects both AC and pulsating DC residual currents.

Trip sensitivity of 1000mA enhances protection against earth faults. Short break time improves safety by minimizing fault duration. DIN rail mounting simplifies installation and panel integration. Screw terminals provide secure electrical connections.

Reset actuator lever allows easy manual reset. Compliant with EAC, VDE, CE, CCC standards for quality and safety assurance.
