Its interrupting capacity hits 220 kA at 240 VAC, 154 kA at 415 V, and 121 kA at 440 V — numbers that put it in the high-fault-current class for main or feeder protection in industrial switchgear. The shunt trip (STL) auxiliary release allows remote tripping, so this breaker fits into a coordinated protection scheme where you need to kill power from a PLC or E-stop circuit. The 63 A rating holds flat from 40 °C to 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. That means in a warm panel — say 55 °C ambient — you still get 62 A continuous, so a 60 A load is fine without upsizing the frame. The 220 kA at 240 V is the headline number for North American 240/480 V distribution; at 415 V it still delivers 154 kA, enough for most European industrial mains. ## Panel integration The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole frame that fits standard Siemens 3VA mounting plates and busbar systems. The shunt trip (STL) is factory-installed, so no field wiring of an add-on module is needed.","metaTitle":"Siemens 3VA1163-6EF32-0KA0 SENTRON MCCB, 63 A, 3-pole, 220 k","metaDescription":"Siemens 3VA1163-6EF32-0KA0 SENTRON molded case circuit breaker, 63 A, 3-pole, 220 kA at 240 V.
