This is a high-frame breaker sized for main feeders or large motor branch circuits in industrial switchgear. The 630 A rating is the uninterrupted current it carries under normal load; the thermal derating curve matters when the breaker lives inside a hot enclosure — at 50 °C it carries 593 A, at 60 °C it carries 557 A, and at 70 °C it carries 520 A. The interrupting ratings are the real headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. The ETU340 is an electronic trip unit with adjustable long-time, short-time, and instantaneous pickup settings — it's not a fixed thermal-magnetic. That means you can coordinate selectivity with downstream breakers by dialing in the time-current curve, which is essential for a main breaker feeding multiple sub-feeders. The unit has no trip indicator, no undervoltage release, and no communication function — it's a standalone overcurrent protector, not a smart breaker. If you need remote monitoring or shunt-trip capability, you'll add those as optional accessories; the product extension for a motor drive is listed as available. ## Panel integration — dimensions and mounting The 162 W maximum power loss at full rated current generates heat that must be dissipated — if you're packing multiple breakers in a small enclosure, factor that into your thermal calculation to avoid nuisance tripping from ambient rise.","metaTitle":"Siemens 3VA2463-7HK32-0AA0 SENTRON MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2463-7HK32-0AA0 molded case circuit breaker, 630 A, 3-pole, ETU340 release.
