Voltage-independent tripping means it clears a ground fault even if the line voltage drops, which is a solid safety feature for a group incomer role in a distribution board. The 25 A continuous rating and 100 mA sensitivity place it as a feeder or submain protector rather than a final-circuit device — you would see this ahead of multiple smaller MCB/RCDs, not protecting a single socket outlet. Rated insulation voltage is 440 V AC, giving headroom for transient overvoltages in a solidly-grounded TN system. Breaking capacity is stated as Idm 500 A / Im 500 A, which is the rated making and breaking capacity for the RCCB under fault conditions. ## Mounting and installation Set of 3 units per package.","metaTitle":"A9KR12425BQ Acti9 ID K RCCB, 25A 100mA 4P, AC Type","metaDescription":"Schneider Electric A9KR12425BQ Acti9 ID K residual current circuit breaker. 25 A rated, 100 mA sensitivity, 4P, Type AC.
