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-performance residual current circuit breaker with overcurrent protection (RCBO), designed to ensure comprehensive electrical safety in modern installations. This 1P+N device integrates both short-circuit and overload protection with earth fault detection in a single compact unit, making it an essential component for protecting circuits in residential and commercial buildings.

Advantages

This device offers a robust solution for electrical distribution by combining two critical safety functions into one space-saving module. Its design ensures high reliability and operational efficiency, providing protection against both overcurrents and leakage currents. The unit is engineered for easy installation and long-term durability, maintaining consistent performance under standard operating conditions while helping to prevent electrical hazards effectively.

Suitable for

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

When it may not be suitable

This device is designed for AC type leakage currents and may not be suitable for circuits where DC components are present, such as those connected to certain types of frequency converters or advanced electronic equipment. It is also not intended for industrial applications requiring higher breaking capacities or specific environmental protections beyond standard indoor electrical enclosures.

Key specifications

• Rated current: 32A
• Breaking capacity: 6kA
• Sensitivity: 30mA
• Type: AC
• Poles: 1P+N
• Protection functions: Short-circuit, overload, and earth fault

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 correctly connected to the input terminals and the load cables to the output terminals, observing the polarity markings for 1P+N configuration. Once installed, the device can be manually switched on or off using the front lever, and the integrated test button should be used periodically to verify the functionality of the residual current protection mechanism.

What to consider before purchase

• Verify that the 32A rated current matches the requirements of your specific circuit.
• Ensure the 30mA sensitivity is appropriate for the intended level of human protection.
• Check that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that the AC type is compatible with the connected electrical loads.

Usage recommendations: It is recommended to perform a functional test of the residual current protection using the integrated test button at least every six months to ensure the device remains in optimal working condition.
