Hager UM22B Universal Copper Busbar 20x10mm 2-Field 500A 495mm

In electrical distribution, connecting multiple devices to a common power source often requires a reliable, low-resistance conductor. The Hager UM22B is a flat copper busbar designed for exactly that: it provides a solid, uninsulated 20x10 mm copper path rated for 500 A, ideal for building two-field distribution setups in control panels and switchgear.

Who is it for

This busbar is intended for electricians, panel builders, and maintenance technicians who need a robust, high-current busbar for universal power distribution. It is particularly suited for applications where two fields or modules must be linked, and where space and current capacity are critical.

Main features

• Solid copper construction for excellent conductivity and durability.
• Flat rectangular cross-section 20 x 10 mm, rated for 500 A continuous current.
• Length of 495 mm, suitable for two-field distribution layouts.
• Uninsulated design allows direct connection to compatible terminals or clamps.
• Part of the Hager UM series, ensuring compatibility with universal mounting systems.
