Product Positioning

The Siemens SENTRON 5SU1656-1KK25 is a residual current circuit breaker (RCBO) with a C-characteristic curve, a rated current of 25A, and 300mA AC residual current protection. It has a breaking capacity of 6kA and is suitable for circuits with low requirements for high-sensitivity residual current protection and where the focus is on preventing fire risks.

Core Product Advantages and Features
C25 Overcurrent Protection
The C-characteristic curve corresponds to loads with high instantaneous starting current, and the 25A rated current is suitable for general power or lighting circuit configurations.
300mA fireproof leakage protection
The 300mA leakage current is designed to be fireproof, reducing the risk of fire caused by leakage, and is suitable for use with systems that already have personal protective equipment at the front end.
One machine, two uses, saves space
Overcurrent and leakage protection are integrated into a single device, eliminating the need for a separate leakage circuit breaker and saving installation space in the distribution box.
