Three-Pole Distribution Block

The EATON BUSSMANN 16220-3 is a three-pole power distribution block built for industrial control panels and machinery wiring. It accepts aluminium or copper conductors and provides a compact means of splitting a single supply into multiple branch circuits.

175 A at 600 V with 14 to 2/0 AWG Line Input

Each pole offers one line connection rated from 14 AWG up to 2/0 AWG copper and four load connections rated from 14 AWG to 4 AWG copper. The block carries a maximum of 175 A per pole at 600 V AC/DC, so it suits main feeder distribution but will not support larger conductors or higher fault-current requirements.

Compact 2.88 in by 2.69 in Footprint

The unit measures 2.88 in overall length by 2.69 in overall depth, allowing dense mounting on DIN rail or back-plate without additional hardware. No covers, markers or mounting accessories are included, so installers must source insulation barriers and labelling separately.

Questions about this item

Will the 175 A, 600 V rating handle the older 14 AWG copper feeds I am keeping?

Yes, the block accepts copper from 14 AWG up to 2/0 AWG on the line side and 14 AWG to 4 AWG on the load side at 175 A, 600 V AC/DC.

How can I confirm the three-pole block is seated and conducting correctly after wiring?

Verify each of the three poles shows tight connections on the single line stud and four load terminals, then measure continuity and expected voltage across poles.

Does the 16220-3 come with mounting hardware or must I source screws separately?

The supplied unit includes the distribution block only; mounting screws or DIN-rail clips are not included and must be purchased separately.
