DSN201E B16 A30 Residual Current Circuit Breaker with Overcurrent Protection

Why Choose the ABB DSN201E B16 A30 RCBO?

The ABB DSN201E B16 A30 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and earth leakage faults. Part of the trusted 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 B tripping characteristic and Type A residual current protection, the DSN201E B16 A30 detects both sinusoidal AC and pulsating DC earth leakage currents commonly produced by modern electronic equipment. It is particularly suitable for socket outlets, lighting circuits and general-purpose final circuits.

With a rated current of 16 A, a residual operating current of 30 mA and a 6 kA breaking capacity, the ABB DSN201E B16 A30 provides dependable protection while occupying only one DIN rail module, helping maximise available space within consumer units and distribution boards.
