Interrupting capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. An undervoltage release (UVR) is built in — part number 3VA9608-0BB24 for the integrated auxiliary trip. That UVR means the breaker drops on loss of control voltage, which is standard for emergency-stop or safety-disconnect circuits where you want the load isolated when the control supply fails. Footprint: 110 mm deep, 138 mm wide, 248 mm tall. That's a standard SENTRON 3VA2 frame size — it occupies the same mounting hole pattern and bus-bar spacing as other 630 A MCCBs in the series. The base switch variant is 3VA2463-5HL32-0AA0; this order code adds the UVR and auxiliary-switch package. If you're swapping into an existing panel, check that the bus-bar drill pattern matches — the 138 mm width is the critical dimension for phase spacing. Maximum power loss is 164.5 W — that's the heat the breaker dumps into the enclosure at full rated current. For a closed panel, that number drives the ventilation or cooling calculation; don't bury it in a sealed box without accounting for the thermal rise. The mechanical endurance is rated at 15,000 operations — that's the latching cycle count before the mechanism needs inspection. For a main breaker that cycles once a day, that's about 40 years of service life. For a frequently switched load, keep it in mind.","metaTitle":"Siemens 3VA2463-5HL32-0CH0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HL32-0CH0 molded case circuit breaker, 630 A rated continuous current, 187 kA interrupting at 240 V.
