The 630 A frame gives you headroom for transformer or bus riser protection without oversizing the breaker body. Breaking capacity is the real selector here: 121 kA at 240 V, 75.6 kA at 415/440 V, 52.5 kA at 500 V, and 9 kA at 690 V. At 690 V the 9 kA figure is lower, but at that voltage you are typically on a drive or motor circuit with lower available fault current. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for a 630 A frame. Depth of 110 mm leaves room for rear-connected bus bars or cable lugs in a standard 400 mm deep enclosure. ## Thermal derating and ambient — the real continuous current Above that, derate linearly: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. If your panel internal ambient runs 50 °C — common in a packed enclosure with multiple breakers — you only get 593 A continuous. That derating curve is the number to use for your BOM, not the 630 A nameplate. The storage range is wider because the breaker is not under load — that limit governs warehouse and shipping, not running conditions. ## Ground-fault monitoring and trip features The trip indicator is not fitted, so you will need to verify trip status via the handle position or an external auxiliary contact. Maximum power loss is 162 W at full rated current. ## Panel integration — what fits where The 138 mm width and 248 mm height fit a standard 3-pole MCCB cutout. Mounting is via the rear screw terminals or optional plug-in base; the 110 mm depth allows rear bus bar connection in a 400 mm deep enclosure with clearance for cable bending radius.","metaTitle":"Siemens 3VA2463-4HM32-0AA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-4HM32-0AA0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, 126-630 A adjustable thermal-magnetic trip.
