Rated 1 A continuous, so it guards a single small load — not a branch circuit. Snaps onto standard DIN rail (mounting support: DIN rail). Occupies 8 x 9 mm pitches — 72 mm wide for the 4P body. Depth 70 mm, height 81 mm. Tunnel terminals accept 1–25 mm² rigid or 1–16 mm² flexible; wire strip length 14 mm, tighten to 2 N·m. That keeps the footprint tight in a distribution board or sub-panel where space is already allocated per pole. IP20 finger-safe front (IEC 60529), so it suits enclosed panels only — not washdown or outdoor without a secondary enclosure. Pollution degree 2, overvoltage category II, tropicalisation class 2 per IEC 60068-1 (handles 95 % RH at 55 °C). That covers most climate-controlled or sheltered industrial environments. The Acti9 K60 series (short name K60H) is Schneider's standard MCB line for distribution boards. If your load draws even 1.1 A steady, this breaker will eventually trip on the thermal element. The 20 000 electrical / 20 000 mechanical cycles match the expected life of a panel-mounted distribution breaker that sees infrequent operation.","metaTitle":"Schneider Electric A9KF71401BQ Acti9 K60 MCB, C-curve 1A 4P","metaDescription":"Schneider Electric A9KF71401BQ Acti9 K60 miniature circuit breaker.
