Siemens Residual Current Circuit Breaker with Overload Protection 10A 2-Pole 30mA Trip Sensitivity 5SU1354-7KK10

Siemens 5SU1354-7KK10 Residual Current Circuit Breaker (RCBO) with Overload Protection is designed to protect personnel and property by combining the functions of a residual current device and miniature circuit breaker in a compact 2-pole design. It offers a 10A current rating and trip sensitivity of 30mA, providing reliable detection of residual sinusoidal AC currents and pulsating DC residual currents for enhanced safety in electrical installations.

The breaker is equipped with Type C tripping characteristics suitable for a range of load types and applications. It mounts conveniently on a standard DIN Rail, featuring screw terminals with clear front conductor access for easy wiring and maintenance. The device’s compact dimensions of 90mm height, 77mm depth, and 36mm width make it suitable for integration in modular electrical panels.

Rated for 230V AC operation and capable of a breaking capacity of 20kA, the Siemens RCBO also includes a toggle switch reset actuator for quick manual reset after tripping. With earth leakage protection Type A, it can detect DC residual currents in addition to AC, improving protection for installations with mixed frequency leakage currents.

This product meets stringent international standards including IEC 60947-2, EN 60898, and EN 61009-1, ensuring safety and compliance for use in industrial, commercial, and residential electrical distribution systems. Manufactured in Romania, it is part of the Better World sustainability initiative targeting extended product life and reduced environmental impact.

Ideal for applications requiring combined personnel and fire protection, Siemens 5SU1354-7KK10 RCBOs are commonly used in industrial automation, building electrical installations, commercial electrical boards, and residential distribution panels.
