ABB THLK2125 2-Pole Subfeed Lug Kit
The ABB THLK2125 is a 2 pole plug-in subfeed lug kit engineered to economically supply power to a subpanel from a compatible ABB panelboard interior. This family is available in ratings from 125A to 200A, allowing installers to select the amperage that matches the downstream subpanel or distribution equipment being fed. Each kit can be configured as either a sub-feed lug or a feed-thru lug, giving installers flexibility when extending power distribution from a main panel to downstream equipment, and ships packaged 1 EA for straightforward stocking and job-site handling.
Key Features
- 2-Pole Configuration: Designed as a 2 pole plug-in kit for compatible ABB panelboard interiors.
- Amperage Range: Available in ratings of 125A, 150A, and 200A, so the kit can be sized to the subpanel feed capacity required for the installation.
- Dual Function: Can be used as a sub-feed lug to power a subpanel or as a feed-thru lug to pass power on to additional distribution equipment.
- Plug-In Design: Plug-in mounting style for straightforward installation into supported panelboard interiors without a full panelboard replacement.
- Economical Solution: Provides a cost-effective way to add subpanel feed capability to an existing panelboard.
- Single-Unit Packaging: Packaged 1 EA per kit for easy inventory tracking.

ABB THLK2125 – Frequently Asked Questions
1) What is the difference between a sub-feed lug and a feed-thru lug, and can the ABB THLK2125 do both?
Both, from the same kit. Used as a sub-feed lug, the THLK2125 taps the panel's bus to send power out to a subpanel. Used as a feed-thru lug, it passes the incoming supply straight through to additional downstream distribution equipment. It's a 2-pole plug-in kit rated up to 125A, so the choice is made at install time, not at order time.
2) Which amperage ABB THLK subfeed lug kit do I need for my subpanel feed?
Three ratings are offered: THLK2125 at 125A, THLK2150 at 150A, and THLK2200 at 200A. Size the kit to the feeder and overcurrent protection ahead of the subpanel, not to the connected load. All three are 2-pole plug-in kits, so the physical install approach is the same and only the lug capacity changes.
3) Can I add a subpanel feed to an existing ABB panelboard without replacing the panel?
That is what the THLK subfeed lug kit is for. It plugs into a compatible ABB panelboard interior and gives you lug terminations to run a feeder to a subpanel, so you avoid swapping out the whole panelboard just to gain a feed point. Confirm the interior you have accepts a 2-pole plug-in lug kit before ordering.
4) Does the ABB THLK2125 work on a 3-phase panelboard?
It is a 2-pole kit, so it lands two conductors. On a 3-phase, 4-wire panelboard you would need a 3-pole lug kit to pick up all three phases. Use the 2-pole THLK for single-phase feeds or a two-pole tap off the bus.
5) Is the ABB THLK2125 a breaker, or does it provide overcurrent protection?
It is not a breaker. The THLK2125 is a lug kit only, rated up to 125A, and it provides terminations for conductors, not overcurrent protection. Any required protection for the subpanel feeder has to come from a breaker or other device in the circuit.
6) What is the ABB part number for the 200A 2-pole subfeed lug kit?
THLK2200 is the 200A version, with THLK2150 at 150A and THLK2125 at 125A covering the lower ratings in the same 2-pole plug-in family.
7) How many pieces come in an ABB THLK2125 subfeed lug kit order?
One kit per order, packaged 1 EA. For a job needing feeds at several panels, order one kit per panel location and confirm the amp rating at each.
