That range tells you where it's comfortable — the 690 V figure is low, so don't spec it for a 690 V bus without checking your available fault current against that ceiling. The interrupting capacity range spans from a minimum 3 150 A to a maximum 5 040 A — that's the breaker's own internal short-time withstand, not the system SCCR. ## Temperature derating — don't lose headroom At 55 °C it's 618 A; at 60 °C it's 607 A; at 65 °C it's 595 A; at 70 °C it's 583 A. If your panel runs hot, you lose about 12 A per 5 °C step above 50 °C — plan your load accordingly. The 3VA1463-4EF32-0AA0 measures 248 mm high, 138 mm wide, and 110 mm deep — a standard MCCB footprint for 630 A frames. It mounts directly into a switchboard or panel via the rear studs; no DIN-rail adapter for this class. ## What's not on this variant This is a bare line-protection breaker — if you need any of those, you're looking at a different 3VA variant.","metaTitle":"Siemens 3VA1463-4EF32-0AA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens 3VA1463-4EF32-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 3-pole, TM240 release.
