Product details

The Schneider Electric A9KR11225BQ is an Acti9 ID K residual current circuit breaker (RCCB) — 2 poles, 25 A rated current, 30 mA earth-leakage sensitivity, Type AC, for 220-240 V AC 50 Hz networks.

Mounts on a 36 mm wide DIN-rail footprint (4 x 9 mm pitches). Terminals accept 1-35 mm² rigid or 1-25 mm² flexible copper; strip 14 mm and torque to 3.5 N.m. IP20 finger-safe with the enclosure closed, IP40 inside a modular enclosure. Tropicalised to IEC 60068-1 class 2, so it handles 95 % RH at 55 °C without derating.

Rated breaking and making capacity: Idm 500 A, Im 500 A. Electrical durability is 4000 cycles under AC-1 resistive load; mechanical durability is 5000 cycles. The trip mechanism is voltage-independent — it will clear an earth fault even if the supply neutral is lost. Impulse withstand tested to 8/20 µs, 200 A per EN/IEC 61008-1. Pollution degree 2, rated insulation voltage 440 V AC.

Frequently asked questions

What is the closest alternative to A9KR11225BQ in the Acti9 range?

Within the Acti9 ID K family, the closest alternative would be a different sensitivity (e.g., 100 mA or 300 mA) or a different pole count (4P) — the 2P, 25 A, 30 mA Type AC configuration is specific to this order code. No pin-compatible drop-in exists with different ratings.

What compliance documentation does Schneider provide for A9KR11225BQ?

The A9KR11225BQ is certified to IS 12640-1 and EN/IEC 61008-1. IP ratings per IEC 60529. Tropicalisation per IEC 60068-1. Standard Schneider documentation includes a declaration of conformity and test reports; RoHS and REACH compliance data is available on request.

Where can I buy A9KR11225BQ?

The A9KR11225BQ is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
