The thermal-magnetic trip unit handles overloads (thermal bimetal) and short circuits (solenoid) in one package. This is a distribution-grade MCB, not a motor-protection device. The 4-pole configuration makes it suitable for three-phase + neutral circuits in TN or TT systems. The 72 mm width occupies 8 module pitches at 9 mm each — plan your DIN-rail fill accordingly. Tunnel-type terminals accept up to 35 mm² rigid or 25 mm² flexible cable; strip 14 mm and torque to 3.5 N.m. IP20 finger-safe front is fine for enclosed panels; no washdown rating.","metaTitle":"Schneider Electric A9KF71440BQ Acti9 K60 MCB, 4P C-curve 40","metaDescription":"Schneider Electric A9KF71440BQ Acti9 K60 miniature circuit breaker, 4 poles, C-curve, 40 A rated current, 10 kA breaking capacity at 415 V AC.
