Hager KDN380A 80A 3 Pole Insulated Fork Busbar 16mm2 12 Module

Description

Three-phase distribution, no active looping.

The Hager KDN380A is an 80A three-pole insulated fork busbar that distributes phase power across up to 12 modular devices on a DIN rail. Rated for 16mm2 conductor at 230-400V, its fork teeth land directly on your breakers for a fast, uniform three-phase connection, saving space and installation time on the switchboard.

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 KDN380A energises all three phases of a row of devices from a single incoming feed across 12 module positions.

Save Installation Time

Because the fork terminals connect directly to each device, there is no looping between phases by hand. That cuts wiring effort, reduces the chance of a loose or missed connection, and gives a cleaner, more uniform three-phase result. The insulated body adds a layer of protection over exposed conductor.

Built for Australian Switchboards

Rated 230-400V with a 4.5kV impulse withstand voltage, the KDN380A suits residential and commercial three-phase 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.

Q: What is the Hager KDN380A used for?
A: It is a three-pole insulated fork busbar that feeds phase power across up to 12 modular devices on a DIN rail, energising all three phases from one incoming connection without hand-looping.

Q: What is the difference between the KDN380A and the KDN280A?
A: Both are 80A fork busbars for 16mm2 conductor spanning 12 modules at 210mm, rated 230-400V. The KDN380A is three-pole (3P), while the KDN280A is two-pole (2P).

Q: What cable size does the KDN380A connect?
A: It is rated for a 16mm2 rigid conductor cross-section and carries up to 80A along the bar.
