## Summary description

The Siemens 5SU1356-0KK06 is a high-quality residual current circuit breaker with overcurrent protection (RCBO). This 2-pole device features a 6A rated current, B-tripping characteristic, and 30mA sensitivity, designed for AC type leakage currents. It provides essential protection against short circuits, overloads, and residual currents in electrical installations, ensuring safety and reliability for residential and commercial power distribution systems.

## Long description

The Siemens 5SU1356-0KK06 is a professional-grade residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This 2-pole 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 to monitor electrical circuits for faults, effectively disconnecting the power supply when it detects short circuits, overloads, or dangerous leakage currents, thereby protecting both the electrical infrastructure and the end users.
Advantages
This device offers a high level of reliability and safety for modern electrical installations. By integrating overcurrent and residual current protection into one component, it saves significant space in distribution boards while simplifying the wiring process. The B-characteristic ensures precise tripping during overcurrent events, making it highly effective for standard residential and light commercial applications. Its robust construction ensures long-term operational stability and consistent performance under various environmental conditions.
Suitable for
Residential electrical distribution boards
Light commercial power circuits
Protection of lighting and socket circuits
General electrical safety in indoor environments
This device may not be suitable for industrial environments where high-frequency interference or DC components are present, as it is specifically designed for AC type leakage currents. It is also not intended for use in circuits requiring higher rated currents or different tripping characteristics, such as those involving large motor starters or heavy industrial machinery.
Key specifications
Number of poles: 2
Rated current: 6A
Tripping characteristic: B
Residual current sensitivity: 30mA
Leakage current type: AC
To install the device, ensure the power supply is disconnected and mount the unit onto a standard DIN rail within the distribution board. Connect the incoming phase and neutral wires to the designated terminals, ensuring that the connections are tightened to the manufacturer's specified torque. Once installed, verify the wiring integrity and perform a functional test using the integrated test button to confirm the device trips correctly under simulated fault conditions.
What to consider before purchase
Verify that the 6A rated current matches the requirements of your specific circuit load.
Ensure the 30mA sensitivity is appropriate for the intended level of personnel protection.
Confirm that the AC type leakage protection meets the regulatory requirements for your installation.
Check the available space in your distribution board for a 2-pole device.
Regularly test the functionality of the residual current circuit breaker using the test button at least every six months to ensure the mechanical tripping mechanism remains operational and provides reliable protection.
