ABB DSH201 C32 AC30 Residual Current Circuit Breaker with Overcurrent Protection 1P+N 32A 6kA 30mA AC

The ABB DSH201 C32 AC30 is a high-quality residual current circuit breaker with overcurrent protection (RCBO) designed to provide comprehensive electrical safety. This 1P+N device combines the functions of a miniature circuit breaker and a residual current device in a single compact unit, protecting electrical circuits against both overloads and short circuits, as well as earth fault currents. It is engineered to meet the rigorous standards of residential and commercial electrical systems, ensuring reliable performance and enhanced protection for both users and equipment.

Advantages

This RCBO offers a space-saving solution by integrating two essential protective functions into one housing, which simplifies installation and reduces the space required in distribution boards. The device features a robust 6kA breaking capacity, making it suitable for standard electrical installations where reliable fault interruption is necessary. Its 30mA sensitivity is specifically calibrated to provide effective protection against indirect contact, significantly reducing the risk of electric shock. The AC type classification ensures consistent detection of sinusoidal alternating residual currents, providing a dependable safety barrier for standard household and office appliances.

Suitable for

• Residential electrical distribution boards
• Commercial office building circuits
• Protection of lighting and socket circuits
• General purpose electrical installations requiring earth fault and overcurrent protection

When it may not be suitable

This device is designed for AC type leakage currents and may not be suitable for circuits where electronic equipment generates pulsating DC components or high-frequency leakage currents, as these may require A or F type RCDs. It is also not intended for industrial environments with high-intensity harmonic interference or specific DC-sensitive applications.

Key specifications

• Rated current: 32A
• Breaking capacity: 6kA
• Sensitivity: 30mA
• Poles: 1P+N
• Type: AC
• Tripping characteristic: C

How to use

The ABB DSH201 C32 AC30 should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are connected to the appropriate terminals and that the load side is correctly wired. After installation, the device should be tested using the integrated test button to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that the 32A rating matches the requirements of your circuit load.
• Ensure the installation environment is compatible with AC type residual current protection.
• Check the available space in your distribution board for a 1P+N modular device.
• Confirm that the breaking capacity of 6kA is sufficient for the prospective short-circuit current at the installation point.

Usage recommendations

Regularly test the device using the test button at least every six months to ensure the internal mechanism remains operational and provides the intended level of safety.
