At 3 A, this is sized for a small motor or control transformer branch, not a main feeder. ## Dual-standard certification and lifecycle Tightening torque 2 N·m. Strip length 14 mm. That covers most panel wiring up to a 4 mm² feed for a 3 A branch. The thermal-magnetic trip unit is non-interchangeable — no field-swap of the trip element, so order the exact rating. Padlockable toggle and a trip indicator (red flag visible when tripped) help the field tech confirm isolation before working downstream. Earth-leakage protection requires a separate vigi block — not integrated.","metaTitle":"Schneider Electric A9F45403 iC60N MCB, D Curve 3 A 4P 50 kA","metaDescription":"Schneider Electric A9F45403 Acti9 iC60N miniature circuit breaker, 3 A rated, D curve, 4 poles, 50 kA breaking capacity at 415 V AC.
