The rated operational voltage is 380...415 V AC at 50 Hz, and it carries a rated breaking and making capacity of Idm 500 A / Im 500 A. This is a voltage-independent RCCB, so it does not require a separate power supply to trip on a fault. Neutral is on the left. Terminals accept 1...35 mm² rigid or 1...25 mm² flexible cable, with a wire stripping length of 14 mm. The device occupies 8 of the 9 mm pitches. IP20 rated (IP40 in a modular enclosure).","metaTitle":"Schneider Electric A9KR14440BQ Acti9 ID K RCCB, 40 A, 300 mA","metaDescription":"Schneider Electric A9KR14440BQ Acti9 ID K RCCB, 40 A rated, 300 mA sensitivity, 4P, Type AC, instantaneous.
