The breaker carries a continuous-current derating curve from 630 A at 40 °C down to 520 A at 70 °C, so if the panel ambient runs hot (say 50 °C inside a non-ventilated enclosure), the usable rating drops to 593 A — plan the load schedule against that number, not the 40 °C sticker. ## Interrupting capacity across voltage bands At 690 V the interrupting capacity drops to 9 kA — this breaker is not intended for 690 V high-fault service. The 5670 A minimum and maximum rating (likely the magnetic trip threshold for short-circuit protection) is a fixed value on this variant — no adjustable short-time pickup, so selectivity with downstream breakers depends on that fixed magnetic band. ## Active production, built-in undervoltage release The basic switch (the replaceable switching mechanism) is order code 3VA2463-5HN32-0AA0 — if the breaker takes a fault that damages the contacts, you can swap the mechanism without pulling the entire enclosure.","metaTitle":"Siemens 3VA2463-5HN32-0CL0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0CL0 molded case circuit breaker, 630 A continuous, 3-pole, 187 kA at 240 V.
