- Description
The ABB F204 B-25/0.3 (2CSF204568R3250) is a 4-pole, 25 A Type B residual current circuit breaker with a 300 mA threshold and a 10 ms high-immunity delay. Rated 230/400 V, Type B sensitivity adds detection of smooth DC earth-fault currents on top of AC and pulsating DC, making it the four-pole counterpart of the 2-pole F202 B-25/0.3 for three-phase loads.

Selection Notes
At 25 A this is the lower-current member of the F204 B-x/0.3 four-pole sub-group, sized for three-phase sub-circuits below the 63 A frame. The Type B classification is the deciding factor over a Type A or AC device at the same current: choose it specifically where the load can generate smooth DC leakage, such as a three-phase frequency converter or battery charger.
