That 63 A holds steady up to 50 °C; at 70 °C it derates to 58 A, so if your panel runs hot, the continuous current drops accordingly. Breaking capacity climbs to 75.6 kA at 240 V, then steps down through 52.5 kA at 415 V and 32 kA at 440 V, landing at 11.9 kA at 690 V. That 75.6 kA at 240 V is the headline number for high-fault panels — it tells you the breaker can safely interrupt a fault up to that level without welding contacts or venting gas into the enclosure. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard three-pole MCCB footprint that drops into most DIN-rail or panel-mount assemblies without re-drilling. Power loss at full rated current is 17.3 W maximum — that's the heat the breaker dumps into the enclosure. In a sealed panel with multiple breakers side by side, that figure drives the thermal derating and ventilation requirement. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The base switch order code is 3VA11633EF360AA0 — that's the bare breaker without the auxiliary block or shunt trip, if you ever need to order the core unit separately.","metaTitle":"Siemens 3VA1163-3EF36-0KH0 SENTRON MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1163-3EF36-0KH0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 75.6 kA breaking at 240 V.
