630 A MCCB for main feeder protection
The 110 mm depth and 138 mm width fit standard panel-mount cutouts; the 248 mm height leaves room for busbar connections above and below.
This breaker is rated 630 A at 40 °C ambient, but the continuous current drops as the panel warms: 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.
Interrupting ratings across voltages
The 3VA2463-6HL32-0CH0 delivers 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V.
Built-in auxiliary and release options
Communication function is not included — this is a standalone thermal-magnetic or electronic-trip breaker, not a networked power meter.
