The Schneider Electric A9KF71301BQ is a 1 A, C-curve, 3-pole miniature circuit breaker from the Acti9 K60 series, rated for distribution applications on AC networks at 50/60 Hz. It is suitable for isolation per the same standard, which simplifies lockout/tagout during panel maintenance.
The 54 mm width (6 x 9 mm pitches) matches the standard 3-pole MCB footprint, so it slots into any populated distribution board without extra spacing. Tunnel-type terminals accept 1–25 mm² rigid or 1–16 mm² flexible copper; strip 14 mm and torque to 2 N·m top or bottom.
