For most final sub-circuits in a TN or TT system this is adequate; if your point-of-supply SCCR is higher, you will need to step up to an industrial MCB or fuse. It will trip faster on a modest overload than a C-curve, which matters when you are coordinating downstream with a 6 A load that has no motor start. Four protected poles in a single 72 mm wide module (8 × 9 mm pitches) let you switch all phases and the neutral in a 3-phase + N distribution board. The thermal-magnetic trip unit covers both overload (thermal bimetal) and short-circuit (solenoid) protection on each pole. ## Integration notes for the panel builder The 72 mm width (4-pole) occupies eight 9 mm pitch positions on the rail — plan your enclosure fill factor accordingly. Storage temperature range of -40 to 85 °C covers most warehouse and transport conditions. The toggle gives a clear ON/OFF indication; no auxiliary contact position indicator is built in.","metaTitle":"A9K23406 Acti9 iK60N MCB, 4P, B-Curve, 6 A, 6000 A Icn","metaDescription":"Schneider Electric A9K23406 Acti9 iK60N miniature circuit-breaker, 4 poles, B-curve, 6 A rated, 6000 A breaking capacity at 400 V AC.
