2CSR255180R2164 ABB Residual Current Circuit Breaker with Overcurrent Protection DS201 – 1P+N – 100 mA – 16 A – C – Type A

Why Choose the ABB DS201 C16 A100 RCBO?

The ABB 2CSR255180R2164, also known as the DS201 C16 A100, is a high quality residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and earth leakage faults. Combining multiple protection functions into a single compact device, it helps simplify installation while improving electrical safety.

Part of the trusted ABB System pro M compact DS201 series, this RCBO features a 1P+N configuration occupying just two DIN modules. It provides protection against sinusoidal AC and pulsating DC earth fault currents using Type A residual current detection, making it suitable for residential, commercial and light industrial electrical installations.

With a rated current of 16 A, a C tripping characteristic and a rated residual operating current of 100 mA, the DS201 C16 A100 delivers dependable protection for final circuits operating from 230 V AC supplies.
