That 630 A rating is at 40 °C ambient; the breaker thermally derates to 520 A at 70 °C, so the actual continuous current your bus can carry depends on enclosure temperature — plan your panel ventilation around the 162 W maximum power loss this unit dissipates at full load. Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V — these are the fault currents the breaker can safely interrupt at each voltage level, which governs your SCCR coordination upstream. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — this is a full-frame 3VA2 breaker sized for 630 A buswork, not a compact frame. Verify your enclosure depth clears 110 mm plus wiring space for the line and load lugs.","metaTitle":"Siemens 3VA2463-5HL32-0JA0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens 3VA2463-5HL32-0JA0 SENTRON molded case circuit breaker, 630 A rated continuous current, 3-pole, line protection with ETU320 release and shunt trip.
