Why Choose the ABB DSN201E C25 A30 RCBO?
The ABB DSN201E C25 A30 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to provide reliable protection for single-phase electrical circuits against overloads, short circuits and earth leakage faults. As part of the proven ABB DSN201E series, it combines multiple protective functions within a space-saving single-module device, making it ideal for residential, commercial and light industrial installations.
Featuring a C tripping characteristic and Type A residual current protection, the DSN201E C25 A30 detects both sinusoidal AC and pulsating DC residual currents generated by modern electronic equipment. The switched neutral design improves safety while the compact construction allows efficient installation within consumer units and distribution boards.
With a rated current of 25 A, a residual operating current of 30 mA and a 6 kA breaking capacity, the ABB DSN201E C25 A30 delivers dependable protection for socket outlets, lighting circuits and other final circuits requiring combined overcurrent and earth leakage protection.
