Busbar for EasyPact — 250 A, 8 Ways
The Schneider Electric EZB250W08 is an 8-way EasyPact busbar rated at 250 A continuous, designed for distributing power across a panel without individual wiring per device. It carries a rated short-time withstand current of 30 kA for 1 s (Icw), meaning it can survive a bolted fault long enough for an upstream breaker to clear — a critical spec for panel SCCR coordination. Rated insulation voltage (Ui) is 690 V AC 50/60 Hz, and rated operational voltage (Ue) is 550 V AC 50/60 Hz, covering standard 400/480 V distribution systems with headroom. The busbar accepts up to 12 two-pole devices, 24 single-pole, or 8 three-pole devices, giving flexibility in how you populate the panel. Built to IEC 60439, this is a pre-assembled busbar system for the EasyPact range — no busbar extension included, so plan your run length accordingly. Dimensions: 416 mm wide, 418.5 mm high, 82.5 mm deep — fits standard enclosure backplates with room for gland plates above or below.
If you need a drop-in replacement for an existing panel design, the closest functional match would be a current-production EasyPact busbar with the same 250 A rating and 8-way configuration — verify the mounting hole pattern and device clip compatibility against your existing EasyPact breakers and switches before committing the BOM line.
Mounts directly onto the EasyPact device terminals — no separate DIN-rail adapter needed. The 416 mm width spans roughly 16.4 inches, so a standard 600 mm wide enclosure gives you side clearance for cable ducts or gland plates. Depth of 82.5 mm means it sits flush with the devices; no extra backspace required beyond the device depth itself. Rated 250 A continuous means the busbar itself does not need derating for most panel ambient temperatures up to 40 °C — but the connected devices' terminal ratings may govern. The 30 kA short-time withstand lets you coordinate with a 30 kA or higher upstream MCCB or fuse without adding a separate current-limiting reactor.
