Designed for 230V electrical systems with a 16A rated current, this Type A device provides reliable protection against short circuits, overloads, and residual currents. With a breaking capacity of 6000A, it ensures safety in residential and commercial installations by preventing electrical faults and enhancing circuit reliability.

## Long description

The Siemens 5SU1356-6KK16 is a professional-grade residual-current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is engineered to provide comprehensive electrical safety by combining the functions of a miniature circuit breaker and a residual current device in a single compact unit. It is designed for use in 230V electrical systems and is rated for a 16A current, making it an essential component for modern electrical distribution boards.
The primary advantage of this Siemens RCBO is its ability to offer dual-layer protection against both overcurrent conditions, such as short circuits and overloads, and residual currents that may indicate a ground fault. By integrating these safety features, the device helps prevent electrical fires and protects users from dangerous electric shocks. Its robust construction and high breaking capacity of 6000A ensure reliable performance even under demanding conditions, contributing to the overall stability and longevity of your electrical infrastructure.
Suitable for
Residential electrical distribution boards
Commercial office building circuits
Protection of individual final circuits
Preventing electrical faults in household appliances
This device may not be suitable for industrial applications requiring higher current ratings or specific breaking capacities beyond its 6000A limit. It is also not intended for use in DC electrical systems or environments where the specific Type A residual current characteristics are not compatible with the connected equipment.
