Product details

The A9KF71263BQ is a 63 A, 2-pole thermal-magnetic miniature circuit breaker from the Schneider Acti9 K60 series. The 63 A rated current and C-curve magnetic trip (5–10 x In) make it a standard choice for general-purpose distribution and moderate motor-starting loads — the C-curve holds through the inrush of small motors and transformers without nuisance tripping, but clears fast enough on a hard short. On a DIN rail, 36 mm wide — two modules — it fits a standard enclosure with 4 pitches at 9 mm.

Integration details

The IP20 finger-safe front is standard for enclosed panels — not for wet or outdoor locations without a secondary enclosure.

Frequently asked questions

What is the breaking capacity of A9KF71263BQ?

10,000 A Icn at 415 V AC, 50/60 Hz, conforming to EN/IEC 60898-1. This is the maximum fault current the breaker can safely interrupt at that voltage.

What curve does this MCB have?

C-curve, with magnetic tripping between 5 and 10 times the rated current. Suited for general distribution and moderate inductive loads like small motors and transformers.

Where can I buy A9KF71263BQ?

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