Rated 63 A continuously at ambient temperatures from 40 °C to 50 °C, it derates slightly to 58 A at 70 °C — the thermal curve matters if your panel runs hot. Breaking capacity is 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V, dropping to 17 kA at 500 V and 690 V. That 220 kA figure at 240 V is the headline: it handles high-fault scenarios at low voltage without cascading upstream. ## Configuration and panel fit Three-pole unit, 70 mm deep, 76.2 mm wide, 130 mm tall — fits standard MCCB panel cutouts. Ships with a shunt trip (STL) release and an auxiliary switch block: 2 auxiliary switches plus 1 trip alarm switch (HQ configuration). No undervoltage release, no ground-fault monitoring, no communication module on this variant. The rated insulation voltage is 800 V, so it's comfortable on 690 V line-to-line systems.","metaTitle":"Siemens 3VA1163-6EF32-0KH0 SENTRON MCCB, 63 A, 220 kA","metaDescription":"Siemens 3VA1163-6EF32-0KH0 SENTRON molded case circuit breaker, 3-pole, 63 A rated at 40-50 °C, 220 kA breaking at 240 V.
