That 630 A figure is the one you size busbars and upstream protection for; the 520 A floor at 70 °C tells you how much headroom you lose in a hot enclosure. Maximum power loss of 162 W means this breaker dumps heat into the panel — account for ventilation if the enclosure is sealed. Breaking capacity is 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. Physical footprint: 110 mm deep, 138 mm wide, 248 mm tall. Fits standard 600 mm-wide MCC buckets and panelboard gutters without clearance issues. The trip indicator provides a visual flag when the breaker has tripped on fault — no need to open the enclosure door to check status. ## Integration Notes Designed as a line-protection MCCB in the SENTRON family — mounts in standard panelboard or MCC bucket cutouts. The 3-pole form factor with no undervoltage release and no ground-fault monitoring means it is a straight thermal-magnetic or electronic-trip breaker for basic feeder protection.","metaTitle":"Siemens SENTRON 3VA2463-7HN32-0AH0 MCCB, 630 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0AH0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, 330 kA breaking at 240 V.
