Hager KDN180G 80A 1 Pole Insulated Fork Busbar 16mm2 18 Module

Description

One bar, eighteen modules, no looping.

The Hager KDN180G is an 80A single-pole insulated fork busbar that distributes phase power across up to 18 modular devices on a DIN rail. Rated for 16mm2 conductor at 415V, its fork teeth land directly on your breakers for a fast, uniform connection across a full-width row, saving time on larger single-phase switchboards.

What Is a Fork Busbar?

A fork (comb) busbar is an insulated bar that clips across a row of modular devices to feed phase power to each one, replacing hand-cut loops of building wire. The KDN180G carries 80A across 18 module positions, so a single bar can energise a wide row of breakers or RCBOs from one incoming feed.

Save Installation Time on Larger Boards

With 18 module positions, the KDN180G suits boards with higher circuit counts where hand-looping every active would be slow. The fork terminals connect directly to each device, cutting wiring effort, reducing the chance of a loose or missed connection, and giving a cleaner, more uniform result. The insulated body adds a layer of protection over exposed conductor.

Built for Australian Switchboards

Rated at 415V with a 4kV impulse withstand voltage, the KDN180G suits residential and commercial switchboards across Australia. At 319mm it spans 18 standard modules, and its 16mm2 conductor is sized to carry the full 80A rating along the bar. Pair it with compatible Hager modular devices for a matched distribution setup.

Q: What is the Hager KDN180G used for?
A: It is a single-pole insulated fork busbar that feeds phase power across up to 18 modular devices on a DIN rail, removing the need to loop active conductors between breakers.

Q: What is the difference between the KDN180G and the KDN180A?
A: Both are 80A single-pole fork busbars for 16mm2 conductor. The KDN180G spans 18 modules at 319mm, while the KDN180A spans 12 modules at 210mm.

Q: How much cable can the KDN180G connect?
A: It is rated for a 16mm2 rigid conductor cross-section and carries up to 80A along the bar.
