ABB 2CSR255080R1204 DS201 C20 AC30 1P+N 20A 10kA Type AC 30mA Earth Leakage Circuit Breaker RCBO

The ABB DS201 C20 AC30 (SKU: 2CSR255080R1204) is a 1P+N Residual Current Circuit Breaker with Overcurrent Protection (RCBO) rated at 20 A with a 30 mA residual current sensitivity and a 10 kA breaking capacity. Designed for Type AC earth leakage detection, the DS201 C20 AC30 provides simultaneous protection against both overload/short-circuit currents and earth leakage faults in a compact DIN-rail mount package — ideal for residential and light commercial distribution boards.
