The Schneider Electric EZB630W06 is a 630 A EasyPact busbar with 6 ways, designed for distributing power across multiple devices 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, with a short-time withstand current of 40 kA for 1 second — meaning it can handle fault currents up to that level without damage during the clearing time of an upstream protective device. The busbar accommodates up to 18 single-pole, 6 three-pole, or 8 two-pole devices, with busbar extension options for 2 or 4 ways.
The 630 A rated current sets the maximum continuous load the busbar can carry — sized for a main distribution bus in a panel feeding multiple branch circuits. The 40 kA short-time withstand for 1 second tells you the busbar can survive a fault of that magnitude until the upstream breaker or fuse clears, which is critical for coordination studies. The 6-way configuration with 107 mm depth, 416 mm width, and 365 mm height defines the physical envelope for panel layout — verify the mounting footprint against your enclosure's gland plate and busbar support spacing.
