ABB 2CSF204101R1250 Residual Current Circuit Breaker

ABB 2CSF204101R1250 is a 4-pole residual current circuit breaker (RCD) from ABB’s System Pro M Compact family, designated F204 A-25/0,03. It is rated for 25 A with a residual current rating of 30 mA (Type A), designed to trip when earth-leakage current exceeds the threshold to protect people and equipment. This four-pole unit protects 4-wire distributions in 3-phase installations and interrupts power quickly upon leakage, helping to prevent electric shocks and electrical fires. As part of ABB’s modular protection system, the 2CSF204101R1250 is designed for DIN-rail mounting in commercial and industrial distribution panels, delivering reliable earth-leakage protection in a compact form.
