The interrupting rating hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and still holds 7.5 kA at 690 V — enough for high-fault industrial service where the upstream transformer can deliver serious current. The 63 A frame is rated at 100 % of its nameplate from 40 °C up to 50 °C; above that it follows a published derating curve — 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Breaking capacity is specified across five voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The 3VA1063-3ED32-0BC0 is a fixed-mount MCCB with a 76.2 mm (3 in) width, 130 mm (5.12 in) height, and 70 mm (2.76 in) depth. The front-facing terminals accept standard lug or busbar connections. No communication module or ground-fault monitoring is built in — those are external add-ons if required.","metaTitle":"Siemens SENTRON 3VA1063-3ED32-0BC0 MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1063-3ED32-0BC0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, line protection, breaking capacity 75.6 kA at 240 V.
