Hager KDN180A 80A 1 Pole Insulated Fork Busbar 16mm2 12 Module

Description

Faster board wiring, no active looping.

The Hager KDN180A is an 80A single-pole insulated fork busbar that distributes phase power across up to 12 modular devices on a DIN rail. Rated for 16mm2 conductor at 415V, the fork terminals land directly on your breakers for a fast, uniform connection, saving space and installation time on 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 KDN180A carries 80A across 12 module positions, so a single bar energises a full row of breakers or RCBOs from one incoming feed.

Save Installation Time

Because the fork terminals connect directly to each device, there is no looping of active conductors between poles. That cuts wiring effort, reduces the chance of a loose or missed connection, and gives a cleaner, more uniform result across the board. The insulated body adds a layer of protection over exposed conductor.

Built for Australian Switchboards

Rated at 415V with a 4.5kV impulse withstand voltage, the KDN180A suits residential and commercial switchboards across Australia. At 210mm it spans 12 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.
