The Schneider Electric EZB630W10 is a 630 A busbar from the EasyPact range, designed for distributing power across up to 10 ways in a panel. It carries a rated insulation voltage of 690 V AC 50/60 Hz and a rated operational voltage of 550 V AC 50/60 Hz, making it suitable for standard low-voltage distribution in industrial switchboards built to IEC 60439. The 630 A rating means this busbar can handle the full load current of a main feeder or large sub-distribution board. The 40 kA short-time withstand for 1 second tells you it can ride through a fault long enough for an upstream breaker to clear, without the busbar itself failing.
If your panel design can accept a parametric substitute, a current-production busbar with the same 630 A rating and 10-way count from the same class would be the closest functional match, but the physical footprint and mounting hole pattern may differ — verify dimensions against the original before committing.
The busbar measures 515 mm high, 416 mm wide, and 107 mm deep. That 107 mm depth is the key dimension for enclosure fit — it determines the minimum internal depth of the switchboard compartment. The 416 mm width and 515 mm height set the cutout and mounting footprint on the panel backplate. It accepts up to 10 three-pole devices, or 14 two-pole, or 30 single-pole breakers. The busbar extension can add 2 or 4 additional ways if the layout needs to grow slightly beyond the base 10.
