The unit's breaking capacity is 6000 A Icn at 230 V AC, tested to EN/IEC 61009-2-1. For coordination, the limitation class is 3 per the same standard, meaning it lets through less energy than a class-3 threshold, which helps the upstream breaker stay selective on a hard fault. ## Earth-leakage and trip technology The integrated earth-leakage protection is set at 300 mA sensitivity — that's a common level for general distribution circuits where you want to guard against insulation faults but avoid nuisance tripping from normal leakage on long cable runs or equipment with filters. The trip unit is thermal-magnetic: the thermal bimetal handles overloads (slow, inverse-time), and the solenoid handles short-circuits (instantaneous above the magnetic threshold). Both the overcurrent and residual-current functions are in one housing, so it saves a DIN-rail position compared to a separate MCB and RCCB. ## Installation and wiring details Torque them to 2 N·m, and strip 14 mm of insulation. The toggle gives local ON/OFF and fault indication, which is handy for a maintenance electrician tracing a tripped circuit without pulling the front cover.","metaTitle":"Schneider Electric A9DF7640 Acti9 iCV40 40A RCBO, 6kA, 300mA","metaDescription":"Schneider Electric A9DF7640 Acti9 iCV40N RCBO, 40A C-curve, 6kA breaking capacity, 300mA earth leakage, current lifecycle stage.
