Three-Pole Power Distribution Block

The Bussmann 16021-3 is an open-type power distribution block rated for 175 A at 600 V. It provides three poles for splitting a single supply into multiple branch circuits in industrial panels. The unit accepts both aluminum and copper conductors on the line and load sides. It mounts directly onto a flat surface within the enclosure.

Verify Conductor Sizes and Mounting Space

Before ordering, confirm that your line conductors fall between 14 AWG and 2/0 AWG for copper. The load side accepts copper wires from 14 AWG up to 4 AWG across six connections per pole. Ensure the panel has at least 2.12 in. of depth clearance for the block body. Check that surface mounting suits your enclosure layout and that the 600 V rating matches your system voltage.

Supplied Hardware Simplifies Termination

The block ships with the necessary pressure connectors for the stated wire ranges, so no separate lug kits are required. Its open design allows visual inspection of every termination after installation. The three-pole layout keeps phases grouped together, reducing wiring errors during initial build or later maintenance. No software or configuration is involved.

Questions about this item

What wires and tools come with the 16021-3 block, and what must I supply?

The block itself is the only item included. You must provide 14 AWG to 2/0 AWG copper line conductors and 14 AWG to 4 AWG copper load conductors, plus mounting hardware for surface installation.

How do I decide between the 175 A copper rating and the 600 V rating for my application?

The 175 A figure is the maximum continuous current per pole with copper wire; the 600 V figure is the maximum voltage the block is rated to insulate. Choose wire gauge and circuit protection so neither limit is exceeded.

What does the 175 A rating mean once the block is mounted in a panel?

Each of the three poles can carry up to 175 A continuously when terminated with copper wire within the 14 AWG to 2/0 AWG range, provided ambient temperature and cable bundling follow standard derating practice.
