## Summary description

The ABB DSH201 B16 AC30 is a 2-pole residual current circuit breaker with overcurrent protection (RCBO). It features a 16A rated current, 30mA sensitivity, and 6kA breaking capacity. Designed for electrical safety, it provides protection against both overload and short-circuit currents, as well as residual currents, ensuring reliable operation in residential and commercial electrical distribution systems.

## Long description

The ABB DSH201 B16 AC30 is a high-quality 2-pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in modern distribution systems. This device combines the functions of a miniature circuit breaker and a residual current device into a single compact unit, effectively protecting circuits against overloads, short circuits, and earth leakage currents. It is designed for seamless integration into residential and commercial electrical panels, ensuring consistent performance and enhanced protection for both users and connected equipment.
Advantages
The primary benefit of this RCBO is its ability to provide dual-layer protection within a space-saving design, reducing the number of components required in an electrical cabinet. By integrating overcurrent and residual current protection, the device ensures rapid disconnection in the event of a fault, thereby minimizing the risk of fire or electric shock. Its robust construction and reliable tripping mechanism offer long-term operational stability, making it a dependable choice for maintaining electrical integrity in various environments.
Suitable for
Residential electrical installations for lighting and socket circuits
Commercial office buildings requiring reliable circuit protection
Protection of individual final circuits against leakage and overcurrent
Upgrading existing distribution boards to modern safety standards
When it may not be suitable
This device is designed for AC type residual current detection and may not be suitable for circuits containing electronic equipment that generates DC components, where an A-type or B-type RCD might be required. Additionally, it is not intended for use in high-voltage industrial distribution networks or environments with extreme environmental conditions that exceed the manufacturer's specified operating temperature range.
Key specifications
Rated current: 16A
Sensitivity: 30mA
Breaking capacity: 6kA
Number of poles: 2
Tripping characteristic: B
Residual current type: AC
How to use
The ABB DSH201 B16 AC30 should be installed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and that the load circuit is securely attached to the output terminals. After installation, the device should be tested using the integrated test button to verify the mechanical tripping function and ensure the residual current protection is operational.
What to consider before purchase
Verify that the 16A rated current matches the requirements of your circuit load
Ensure the 30mA sensitivity is appropriate for the intended level of human protection
Check that the B-type tripping characteristic is suitable for your specific application
Confirm that the electrical system requires AC-type residual current protection
Usage recommendations
Regularly test the device using the integrated test button at least every six months to ensure the internal mechanism remains free and functional. If the device trips, investigate the cause of the fault before attempting to reset the switch.
