630 A MCCB with adjustable trip and high interrupting capacity
Its adjustable thermal-magnetic trip unit covers a range from 945 A to 5670 A, giving you flexibility to match the cable or busbar rating without swapping the breaker frame. Breaking capacity is 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Communication function is not included — this is a standalone protective device, not a networked power meter.
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 ambient runs 50 °C, you're limited to 593 A continuous — plan the load accordingly. Maximum power loss is 162 W at rated current.
The 110 mm depth (4.33 in) is the body depth behind the panel face — verify your enclosure depth clearance, especially if a rear-mounted bus or cable duct is present. The basic switch assembly is order code 3VA2463-6HL32-0AA0. The breaker mounts via the SENTRON 3VA family's standard DIN-rail or screw-mount pattern — no special adapter required for most distribution panels.
