That 63 A holds flat through 50 °C — only starts derating at 55 °C (62 A) and drops to 58 A by 70 °C, so it carries its full rating in most ventilated enclosures without forced cooling. The interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and still delivers 11.9 kA at 690 V — that's serious fault-current headroom for a 63 A frame, meaning it can sit downstream of a large transformer without needing a current-limiting fuse upstream for coordination. This is a line-protection design — no ground-fault module, no communication module, no undervoltage release. What it does carry is a shunt trip (STL) and a full complement of auxiliary switching: two auxiliary contacts plus a separate trip alarm switch (HQ). That's enough for remote status indication and a shunt-trip emergency-off circuit without adding external relay logic. ## Physical fit and wiring — panel integration notes The 76.2 mm width (3 inches) is standard for a 3-pole frame in this range; it occupies three 25 mm DIN positions if mounted on a DIN rail adapter, or bolts directly to the mounting plate.","metaTitle":"Siemens SENTRON 3VA1163-3EF36-0JH0 MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0JH0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 75.6 kA breaking at 240 V.
