The 2CSF202001R1250 F202 AC-25/0,03: The ABB 2CSF202001R1250 is an F202-series residual current circuit breaker (RCCB) — 25 A rated, 2-pole, 30 mA trip sensitivity, Type AC waveform detection, for 230 V line-to-neutral or line-to-line circuits. The 30 mA sensitivity covers basic personnel protection (shock risk) and fire prevention in standard AC distribution.
Two-pole form factor occupies two modular-width spaces. Terminals accept copper conductors up to the rated cross-section for the 25 A path.
