Why Choose the ABB DS202CRMC10APR30 RCBO?
The ABB DS202CRMC10APR30 is a compact and reliable 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and residual-current faults. As part of the ABB DS202CR M series, it combines overcurrent and residual-current protection in a space-saving modular device for residential, commercial and industrial electrical distribution systems.
This RCBO provides a 10 A rated current, C tripping characteristic and ABB APR high-immunity residual-current protection. The APR characteristic provides increased resistance to unwanted tripping caused by transient disturbances while maintaining effective residual-current protection, making it particularly useful for circuits containing electronic equipment and loads that may generate transient leakage currents.
With a rated residual operating current of 30 mA, the DS202CRMC10APR30 provides additional protection against electric shock while also protecting connected wiring and equipment from overcurrent conditions. Its compact 2-pole configuration provides a practical solution for final circuits where dependable protection and improved continuity of service are required.

High-Immunity Residual-Current Protection
RCBOs combine the protective functions of a miniature circuit breaker and a residual-current device in a single unit. The ABB DS202CRMC10APR30 protects connected circuits against excessive current caused by overloads and short circuits while simultaneously monitoring for residual currents that may indicate an earth fault.
ABB APR residual-current protection is intended for applications where improved immunity to transient disturbances is beneficial. This helps reduce unwanted operation caused by temporary leakage-current peaks or electrical disturbances, supporting improved continuity of service while retaining sensitive 30 mA residual-current protection.
Typical Applications
- Residential electrical distribution systems.
- Commercial buildings and distribution boards.
- Industrial control and auxiliary circuits.
- Circuits supplying electronic equipment.
- Lighting and lower-current final circuits.
- Applications susceptible to transient leakage currents or nuisance tripping.
- Installations requiring combined overcurrent and 30 mA residual-current protection.
