Why Choose the ABB DSN201E C6 A30 RCBO?
The ABB DSN201E C6 A30 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. As part of the dependable ABB DSN201E series, it combines residual current and overcurrent protection within a space-saving single-module device.
This electronic RCBO features a C tripping characteristic and Type A residual current protection. It can detect sinusoidal alternating residual currents and pulsating DC residual currents, making it suitable for modern electrical circuits containing electronic equipment and power supplies.
With a rated current of 6 A, a residual operating current of 30 mA and a short-circuit breaking capacity of 6 kA, the DSN201E C6 A30 provides reliable protection for lighting, control and other low-current final circuits. Its 1P+N switched-neutral configuration and one-module width help reduce installation space inside electrical distribution boards.
Key Advantages
- Combined residual current and overcurrent protection in one device.

Combined Circuit and Earth Leakage Protection
The ABB DSN201E C6 A30 combines the functions of a miniature circuit breaker and a residual current device. Its overcurrent protection disconnects the circuit during overload or short-circuit conditions, while its residual current function responds when potentially hazardous leakage current flows to earth.
Type A residual current detection makes the RCBO suitable for circuits supplying equipment with electronic components that may generate pulsating DC leakage currents. The switched neutral and compact one-module construction support safe isolation and efficient installation in modern electrical distribution systems.
Typical Applications
- Domestic and commercial lighting circuits.
- Building control and automation circuits.
- Small electrical loads and final circuits.
- Commercial distribution boards.
- Residential consumer units.
- Circuits supplying electronic equipment.
