## Summary description

The ABB DSH201 C20 AC30 is a 1P+N residual current circuit breaker with overcurrent protection (RCBO). It features a 20A rated current, 6kA breaking capacity, and 30mA sensitivity for AC type leakage currents. Designed for reliable circuit protection, this instantaneous device prevents electrical faults and overloads in residential and commercial installations, ensuring safety and compliance with electrical standards.

## Long description

The ABB DSH201 C20 AC30 is a high-quality residual current circuit breaker with overcurrent protection (RCBO) designed to provide comprehensive electrical safety in a single compact unit. This 1P+N device combines the functions of a miniature circuit breaker and a residual current device, effectively protecting circuits against both short-circuit currents and overload conditions, while simultaneously detecting leakage currents to prevent electric shock. Engineered for reliability, it ensures consistent performance in residential and commercial electrical systems.
Advantages
This RCBO offers a space-saving solution by integrating two essential protection functions into one modular component, which simplifies installation and reduces the space required in distribution boards. The device features a robust 6kA breaking capacity, ensuring it can safely interrupt fault currents in standard electrical installations. Its 30mA sensitivity is specifically calibrated to provide protection against direct contact, significantly enhancing safety for users. The AC type design is optimized for detecting sinusoidal alternating residual currents, making it a dependable choice for general-purpose applications.
Suitable for
Residential electrical distribution boards
Commercial office building circuits
Protection of lighting and socket outlets
General-purpose electrical installations requiring overload and leakage protection
When it may not be suitable
This device is designed for AC type leakage currents and may not be suitable for circuits containing electronic equipment that generates pulsating DC or high-frequency leakage currents, where an A or F type RCD might be required. It is also not intended for industrial environments with high-power machinery that requires higher breaking capacities or specific tripping characteristics.
Key specifications
Rated current: 20A
Breaking capacity: 6kA
Sensitivity: 30mA
Type: AC
Poles: 1P+N
Tripping characteristic: C
How to use
The device should be installed by a qualified electrician in a standard DIN-rail distribution board. Ensure that the supply cables are connected to the appropriate terminals according to the wiring diagram provided on the device housing. Once installed, the RCBO should be tested periodically using the integrated test button to verify that the mechanical tripping mechanism is functioning correctly and that the circuit is interrupted as expected during a simulated fault.
What to consider before purchase
Verify that the 20A rated current matches the requirements of your specific circuit load.
Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
Confirm that the AC type protection meets the safety standards for the equipment connected to the circuit.
Check the available space in your distribution board for a 1P+N modular device.
Usage recommendations
Regular maintenance and testing are essential for ensuring long-term safety. It is recommended to press the test button at least every six months to confirm the device remains operational and provides the intended level of protection against electrical faults.
