The Schneider Electric EZB250W10 is a 250 A, 10-way busbar from the EasyPact range, used to distribute power to up to ten devices in a panel. Rated insulation voltage is 690 V AC 50/60 Hz, and operational voltage is 550 V AC 50/60 Hz, so it fits standard 400 V and 480 V distribution panels with headroom to spare. It accepts up to ten 3-pole devices, or fourteen 2-pole, or thirty 1-pole — the same busbar covers mixed configurations on a single panel layout.
No official successor order code is listed by Schneider for this part. If you are looking for a drop-in replacement, the closest match will be a current-production EasyPact busbar with the same 250 A rating and way count — but verify the mounting hole pattern and device compatibility against your panel layout before committing the order.
Dimensions are 416 mm wide, 493.5 mm high, and 82.5 mm deep — sized for a standard distribution panel backplate. No busbar extension is included; plan for separate tap-off or extension bars if the panel layout exceeds ten ways. The busbar is designed for connection duty (device application: Connection) and complies with IEC 60439, the standard for low-voltage switchgear and controlgear assemblies. That means it is tested for the thermal and mechanical stresses of a distribution panel environment.
