At 415 V it still delivers 121 kA, dropping to 9 kA at 690 V; that 690 V figure tells you this is a 600 V class breaker being pushed to its ceiling — spec it at the voltage you actually run, not the nameplate maximum. Thermal derating is baked in: 630 A at 40 °C, 570 A at 50 °C, 510 A at 60 °C, 450 A at 70 °C. The 3VA2463-5JP32-0KH0 carries a shunt trip (STL) and two auxiliary switches plus a trip alarm switch HQ — field-configurable, not a sealed assembly. If a line-down situation hits, the aux switch pack can be swapped on site without pulling the breaker from the panel. The storage range exceeds the operating range — that's handling and shipping limits, not running conditions. Max power loss is 162 W at full rated current. That's not trivial — factor it into your enclosure thermal calculation, especially if the MCCB shares a compartment with other heat sources. Line protection design with a trip indicator and voltage trigger — the trip indicator gives a visual flag on the breaker face, useful for a quick walk-down after a fault without opening the panel door. The adjustable trip range runs from 945 A minimum to 5,670 A maximum — that's the short-time and instantaneous pickup adjustment band.","metaTitle":"Siemens 3VA2463-5JP32-0KH0 SENTRON MCCB, 630A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2463-5JP32-0KH0 molded case circuit breaker, 630A continuous at 40°C, 187kA breaking at 240V.
