The ABB 2CSF204001R1250 F204 AC-25/0,03 is a 4-pole residual current circuit breaker (RCCB) rated 25 A with 30 mA sensitivity, Type AC. This is the core ground-fault protection device for TN and TT distribution boards—sized for a 25 A submain or feeder, the 30 mA trip threshold provides personal protection against direct contact. Type AC detection covers sinusoidal AC residual currents only; if your load includes pulsed DC or smooth DC (VFDs, UPS, EV chargers), this is not the right variant.
