Product details

The Schneider Electric A9KF21210BQ is an Acti9 K60 miniature circuit-breaker (MCB) — a 2-pole, 10 A, B-curve unit rated for AC distribution panels.

At 36 mm wide (4 x 9 mm pitches), it occupies two modular spaces in a distribution board. Tunnel terminals top and bottom accept 1–25 mm² rigid or 1–16 mm² flexible — strip 14 mm, torque to 2 N.m. IP20 rated, so it lives inside an enclosed panel, not on the wet side of the wall.

Current-production part — no end-of-life notice. The Acti9 K60 family is Schneider's standard residential and light-commercial MCB line; this order code is the 10 A, B-curve, 2-pole variant.

Frequently asked questions

What is A9KF21210BQ's breaking capacity?

10,000 A Icn at 415 V AC, 50/60 Hz, certified to EN/IEC 60898-1. That is the maximum prospective fault current it can safely interrupt.

What compliance documentation does this brand provide for A9KF21210BQ?

The MCB is certified to EN/IEC 60898-1, carries IP20 per IEC 60529, and meets tropicalisation class 2 per IEC 60068-1 (95% RH at 55 °C). Standard Schneider declarations of conformity cover CE/UKCA marking for EU/UK markets.
