Look beyond the product name. These four checks help narrow the right configuration.
MISSION.A little precision. A smarter selection.
225A - MLA1
Select MLA1 for compatible 225A ReliaGear Pro-Stock main-lug applications requiring pressure-type lugs with a conductor range of 6 AWG through 350 kcmil.
400A - MLA41
Select MLA41 for compatible 400A ReliaGear Pro-Stock main-lug applications requiring pressure-type lugs accepting 2 AWG through 600 kcmil or two 1/0 through 250 kcmil conductors.
Main Conductor Termination
The main lug kit provides the termination point for incoming conductors in a compatible main-lug-only panelboard configuration.
Feed-Through Applications
ABB also specifies lug-kit selection for compatible feed-through applications where additional conductor termination is required.
Before you select
Match the equipment. Check the fit.Equipment Fit
Match the lug kit to the exact switch or panelboard configuration. Similar ampere ratings do not establish terminal compatibility.
Conductor Range
Confirm wire size, conductor material and permitted conductor count. Use the range specified for the selected lug catalog number.
Installation Details
Check the terminal position, conductor preparation and manufacturer torque requirements for the complete assembly.

Important Product Questions
Can I choose a lug kit by ampere rating alone?
No. Confirm equipment compatibility, conductor material, wire size and allowed conductor count. The terminal design must match the approved assembly.
Can multiple conductors share one lug?
Only when the selected terminal is rated for that conductor number, material and size. Check the exact lug specifications before making connections.
What must match when replacing a terminal kit?
Match the kit catalog number to the equipment, then check wire range, terminal position and installation requirements. Follow the specified tightening torque.
Important Model Distinction
Wire range, conductor count and equipment compatibility are specific to the lug kit. Do not transfer one kit’s termination limits to another catalog number.
