ABB OT/OS400 Series Replacement Disconnect Switch Lug Kit

The ABB OT/OS400 Series Replacement Disconnect Switch Lug Kit is a replacement and service accessory engineered for use with ABB's OT/OS400 series disconnect switches. Each kit provides lugs sized to accept a 2-600 AWG conductor range, giving electricians and panel builders the flexibility to terminate a wide span of wire gauges on a single switch platform without stocking multiple lug variants. Kits are packaged 6 to a bag, making this lug kit a practical stocking item for service trucks, maintenance shops, and panel-building operations that need OT/OS400-compatible lugs readily on hand for repairs, retrofits, and service upgrades.

Key Features

  • Wire Range: Accepts 2-600 AWG conductors, covering a broad range of feeder and branch-circuit wire sizes with a single lug kit.
  • Switch Compatibility: Purpose-built for ABB's OT/OS400 series disconnect switches, ensuring proper fit and reliable termination at the switch line and load terminals.
  • Convenient Packaging: Supplied 6 lug kits per bag, simplifying inventory management and restocking for electrical contractors, panel builders, and maintenance teams.
  • Genuine ABB Part: Manufactured by ABB for use as a factory-matched accessory with the OT/OS400 disconnect switch line, supporting proper installation and long-term serviceability.
  • Service-Ready Design: Sized specifically for the OT/OS400 platform so replacement lugs restore original fit and function without improvising a substitute part.
  • Stocking Efficiency: The 6-pack format lets service trucks and maintenance shops keep an adequate supply of matched lugs on hand for multiple OT/OS400 service calls or panel builds.

ABB OZXA-400 – Frequently Asked Questions

1) What wire sizes will the ABB OZXA-400 lug kit accept?
The OZXA-400 lug kit takes conductors from 2 AWG up through 600 AWG, so one kit covers both feeder-sized and smaller branch-circuit conductors landing on the switch. That range is why panel builders can stock a single lug variant instead of several for the OT/OS400 platform.
2) Will the OZXA-400 lug kit fit any ABB disconnect switch, or only the OT/OS400?
Only the OT/OS400 series. ABB builds the OZXA-400 as a matched accessory sized specifically for that switch platform, at both the line and load terminals. If your switch is a different ABB frame size, the lugs will not be the correct fit and you need the kit matched to that frame.
3) I need to replace damaged lugs on an existing ABB OT/OS400 switch. Is this the right part?
That is exactly what the OZXA-400 is for. It is a replacement and service accessory, sized to restore the original fit and termination on an OT/OS400 switch after a lug is damaged, overheated, or lost during a retrofit. Because it is the genuine ABB part for the platform, you are not improvising a substitute lug on service equipment.
4) Can a Square D PowerPacT lug kit be used on an ABB OT/OS400 disconnect switch?
No. The OZXA-400 lug kit is built to the ABB OT/OS400 disconnect switch terminal pattern and is the part to order for that switch. The Square D mechanical lug kits are circuit breaker accessories tied to their own frames - AL1200P7KU to the PowerPacT P frame, CU250JD to the PowerPacT J frame, and AL400L61K3 to the PowerPacT L frame. Frame-specific lug kits mount to the breaker's own terminal pads and will not land correctly on an ABB switch, so match the kit to the equipment brand and series.
5) I need lugs for a circuit breaker, not a disconnect switch - what should I order instead of the ABB OZXA-400?
The OZXA-400 is a disconnect switch accessory for the ABB OT/OS400 series, so for a molded case breaker you want a frame-matched breaker lug kit. Square D offers the CU250JD for the PowerPacT J frame, the AL400L61K3 for the PowerPacT L frame in a 250A 3-pole aluminum configuration, and the AL1200P7KU for the PowerPacT P frame. Identify the breaker frame letter on the nameplate first, since these kits are not interchangeable between frames.
6) How many lugs come in the ABB OZXA-400 kit?
Packaged 6 per bag. For a three-pole switch that covers line and load on all three poles from one bag, which is why it works as a truck stock item rather than something you order per call.
7) What is a comparable 6-pack lug kit from another brand if I am not on ABB gear?
Square D's TeSys GS 200A lug kit also ships as a set of 6, so it fills the same stocking role on Square D TeSys GS switch gear. It is not a substitute on an ABB OT/OS400 switch, though, since lug kits are frame-specific. Pick by the device you are terminating to, not by the pack count.
8) Can I use the OZXA-400 lugs on a larger ABB frame if I am only landing small conductors?
No. The lug body has to bolt to the terminal pad of the switch it was built for, and the OZXA-400 is dimensioned for the OT/OS400. Conductor size is not what governs the fit here, the switch frame is. Order the lug kit ABB publishes for whatever frame is in the enclosure.
9) Is there another lug kit that comes six to a package like the ABB OZXA-400?
Yes. The ABB OZXA-400 is supplied 6 lug kits per bag for OT/OS400 disconnect switches, and Square D's TeSys GS lug kit GS1AW403 is also sold as a set of 6, rated 200A for the TeSys GS switch line. If the six-count packaging is what you are matching for stocking purposes, those two line up; the equipment they terminate on is different, so choose by the switch platform you are servicing rather than by pack quantity.
10) What is the difference between the ABB OZXA-400 lug kit and the Square D TeSys GS1AW403?
Both are disconnect switch lug kits sold in sets of six. The ABB OZXA-400 is matched to the OT/OS400 series switch and its lugs accept a 2 to 600 AWG conductor range on a single platform. The Square D GS1AW403 belongs to the TeSys GS series and is specified at 200A. They serve different switch families, so the deciding factor is which brand of disconnect is in the enclosure.
11) My feeder conductors are large - does the ABB OZXA-400 cover more wire sizes than the Square D lug kits?
The ABB OZXA-400 lugs are sized to accept a 2 to 600 AWG conductor range, which lets one kit cover a wide span of feeder and branch-circuit sizes on the OT/OS400 switch. The Square D comparables are specified by the frame or switch they serve rather than a stated wire span: AL1200P7KU for PowerPacT P, AL400L61K3 as a 250A 3-pole aluminum kit for PowerPacT L, and GS1AW403 as a 200A TeSys GS kit. For a large ABB OT/OS400 feeder termination, the OZXA-400 is the matched part.
