## Summary description

The Siemens 5SU1356-6KK06 is a high-quality residual current circuit breaker with overcurrent protection (RCBO). This 2-pole device features a 6A rated current, B-characteristic curve, and 30mA sensitivity for type A residual current protection. With a 6kA breaking capacity, it ensures reliable electrical safety and circuit protection in residential and commercial installations against short circuits and earth leakage faults.

## Long description

The Siemens 5SU1356-6KK06 is a professional-grade residual current circuit breaker with overcurrent protection (RCBO), designed to provide comprehensive electrical safety in modern installations. This 2-pole device integrates both short-circuit protection and earth leakage detection into a single compact unit, making it an essential component for safeguarding electrical circuits in residential and commercial buildings. By combining these functions, it effectively prevents damage from overcurrents while protecting users against hazardous leakage currents.
Advantages
This RCBO offers a high level of reliability and safety by combining two protective functions in one device, which saves significant space in the distribution board. The Type A sensitivity ensures detection of both alternating and pulsating direct residual currents, providing a broader range of protection compared to standard AC types. Its robust construction and high-quality engineering ensure long-term operational stability and consistent performance under various load conditions.
Suitable for
Residential electrical distribution boards
Commercial office building circuits
Protection of lighting and socket circuits
Systems requiring Type A residual current protection
This device may not be suitable for industrial applications requiring higher breaking capacities than 6kA or for circuits with significantly higher rated currents than 6A. It is also not intended for use in environments with extreme temperatures or high levels of corrosive substances that exceed standard installation guidelines.
Key specifications
Number of poles: 2
Rated current: 6A
Tripping characteristic: B
Residual current sensitivity: 30mA
Residual current type: A
Breaking capacity: 6kA
Weight: 272 g
How to use
The device should be installed by a qualified electrician in a standard DIN-rail distribution board. Ensure that the supply voltage matches the device specifications before connection. The input terminals are located at the top, and the output terminals at the bottom. Once installed, the device can be manually switched on or off using the toggle lever. The integrated test button should be pressed periodically to verify the mechanical functionality of the residual current protection mechanism.
What to consider before purchase
Verify that the 6A rated current is appropriate for your specific circuit load
Ensure the 6kA breaking capacity meets the requirements of your electrical installation
Confirm that Type A protection is required for your specific equipment
Check available space in your distribution board for a 2-pole device
Usage recommendations
Regularly test the device using the integrated test button at least every six months to ensure the residual current protection mechanism remains fully operational. If the device trips, investigate the circuit for potential faults before resetting.
