ABB MLA A-Series Main Lug Kit, Pressure-Type Lugs, 400A-600A

The ABB MLA Main Lug Kit is engineered for ABB's A-Series Panelboards, part of the Pro-Stock unassembled lighting panel program, and is offered in amperage ratings from 400A to 600A to match project load requirements. This lug kit equips a panelboard interior for main lug and/or feed-thru applications and is suitable for use with either copper or aluminum bus. Lugs are pressure-type, accepting a wire range of 2-600 MCM or (2) 1/0-250 MCM, giving electrical contractors flexibility when terminating a range of conductor sizes across the 400A and 600A configurations of A-Series panelboard installations.

ABB MLA41 – Frequently Asked Questions

1) What wire sizes will the ABB A-Series main lug kit accept?
The pressure-type lugs in the ABB A-Series main lug kit take 2-600 MCM, or two conductors per lug at 1/0-250 MCM. That range covers most feeder terminations on a lighting panel interior, including double-lugged parallel runs at the smaller end.
2) Can I use this ABB lug kit on a panelboard with aluminum bus, or is it copper only?
Either one. The A-Series main lug kit is suitable for interiors with copper bus or aluminum bus, so you don't need to order a different kit based on which bus material the interior was built with.
3) Which ABB main lug kit do I order, MLA41 or MLA61?
The two kits are sized by ampacity: MLA41 is the 400A kit and MLA61 is the 600A kit. Match the kit to the ampere rating of the A-Series interior you are equipping.
4) What panelboards does the ABB MLA lug kit fit?
It is built for ABB A-Series panelboards under the Pro-Stock unassembled lighting panel program. It is a panelboard accessory, not a standalone terminal block, so it is not intended for other manufacturers' interiors.
5) Will this kit work for a feed-thru panel, or only a main lug panel?
Both. The A-Series lug kit equips a panelboard interior for main lug and/or feed-thru applications, so the same kit covers a straight main lug configuration or a feed-thru arrangement where the feeder continues on to a downstream panel.
6) Are these mechanical set-screw lugs or crimp lugs?
Pressure-type. You terminate the conductor mechanically in the lug body rather than crimping a separate barrel onto the wire, which means no crimp tool or die set is needed on site to land the feeder.
7) I'm assembling a Pro-Stock lighting panel. Is the lug kit included with the interior or ordered separately?
Separately. The Pro-Stock program ships panels unassembled, and the MLA kit is the accessory that completes the interior for main lug or feed-thru termination. Budget one kit per interior and match the ampere rating, 400A or 600A.
8) How many lug kits come in an ABB MLA order?
Each MLA main lug kit is supplied 1 EA, so a panel builder ordering interiors one at a time gets one kit per line item. If you're equipping both a main lug position and a feed-thru position on separate interiors, order accordingly.
