Hager KDN380G 80A 3 Pole Insulated Fork Busbar 16mm2 18 Module

Description

Three-phase distribution, eighteen modules wide.

The Hager KDN380G is an 80A three-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 three-phase connection across a full-width row, saving time on larger switchboards.

What Is a 3 Pole 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. A three-pole version carries three conductors along one bar, so the KDN380G energises all three phases of a wide row of devices from a single incoming feed across 18 module positions.

Save Installation Time on Larger Boards

With 18 module positions, the KDN380G suits three-phase boards with higher circuit counts where hand-looping every phase 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 KDN380G suits residential and commercial three-phase switchboards across Australia. Its 16mm2 conductor is sized to carry the full 80A rating along the bar, and 18 module positions handle wider device rows. Pair it with compatible Hager modular devices for a matched distribution setup.

Q: What is the Hager KDN380G used for?
A: It is a three-pole insulated fork busbar that feeds phase power across up to 18 modular devices on a DIN rail, energising all three phases from one incoming connection without hand-looping.

Q: What is the difference between the KDN380G and the KDN380A?
A: Both are 80A three-pole fork busbars for 16mm2 conductor. The KDN380G spans 18 modules and is rated 415V, while the KDN380A spans 12 modules and is rated 230-400V.

Q: What cable size does the KDN380G connect?
A: It is rated for a 16mm2 rigid conductor cross-section and carries up to 80A along the bar.
