Square D S37423 – Frequently Asked Questions
1) Will the Square D S37423 control wire terminal lug kit fit a PowerPacT J-frame breaker, or only H-frame?
It works on both. The S37423 control wire terminal lug kit is built for PowerPacT H- and J-frame molded case breakers, terminating control wiring at either the top or the bottom of the breaker so you can route to whichever side suits the panel layout.
2) What is this control wire lug kit actually for on a circuit breaker?
It gives control wiring a dedicated, screw-clamped termination point on a PowerPacT H or J frame breaker. The usual reason to add it is status reporting: the breaker reports its current state back through the connected control wiring to a remote monitoring or control circuit. Panel builders and OEMs also use it for general-purpose control terminations during panel assembly.
3) Can I use a Square D control wire lug kit on an ABB XT or Eaton breaker?
No. Breaker accessory kits are frame-specific. The S37423 is made for Square D PowerPacT H and J frames. For ABB you would use the matching XT series kit, for example the XT4 front terminal kit for copper-aluminum cable or the XT2 low terminal covers; for Eaton, accessories are series-matched like the Series G three-pole terminal shield.
4) Can an Eaton Series C 225A line and load terminal kit be used in place of the Square D S37423 control wire terminal lug kit?
No - the two do different jobs. The Square D S37423 is a control wire terminal lug kit for PowerPacT H- and J-frame breakers, providing a screw-mounted termination point for control wiring so the breaker can report its status, supplied as a set of 2 and tightened to a specified torque. The Eaton 3TA225FD is a set of line and load terminals for Series C molded case breakers, a 225A pressure type connector for copper or aluminum power conductors. One terminates small control conductors, the other terminates the main power cable, and neither substitutes for the other.
5) Does the Square D S37423 lug kit cover the breaker terminals the way a terminal shield does?
No. The S37423 is a control wire terminal lug kit that mounts by screws at the top or bottom of a PowerPacT H- or J-frame breaker to land control wiring; it is a connection point, not a shield. Insulating barriers are separate parts in other lines - the Eaton EFTS3K is a three-pole terminal shield for Series G breakers, the ABB KXT-HTC3 is a three-pole high terminal cover for XT4, and the ABB KXT2LTC-3 is a two-piece set of low terminal covers for three-pole XT2 breakers. If your inspection calls for finger-safe terminal shrouding, that is a cover part, not this lug kit.
6) How many lugs come in the Square D S37423 kit?
Two. The S37423 ships as a set of 2 control wire terminal lugs, which covers multi-pole control wiring on one breaker. If you are outfitting several breakers in a panelboard, count two per kit and order accordingly.
7) What torque do I tighten the PowerPacT H control wire lugs to?
Square D specifies a tightening torque of 1-1 N.m for these control wire terminals. They are screw-type terminations, so use a calibrated torque screwdriver rather than feel to get the terminal seated properly.
8) Do I need extra hardware to install the Square D control wire terminal lug kit?
No separate purchase is needed for the mounting. The kit mounts by screws and includes the PKGTALP2 ground bar kit, so it arrives as a complete accessory package for the breaker.
9) Can I add this control wire terminal kit to breakers already installed in a panel?
Yes, it is used on retrofit work as well as new builds. Because it fastens by screws at the top or bottom of the PowerPacT H or J breaker, existing panelboard installations can be fitted with control wire terminations without replacing the breaker. De-energize the equipment first.
10) I am standardizing a panel shop on one breaker line - how do Square D and ABB accessory kits differ in what comes in the box?
They are packaged to their own frames and quantities. The Square D S37423 control wire terminal lug kit ships as a set of 2 and includes the PKGTALP2 ground bar kit, mounting by screws at the top or bottom of a PowerPacT H- or J-frame breaker. ABB's comparable hardware is sold per frame and per pole count instead: the KXT-3PC front terminal kit for copper-aluminum cable is a three-piece set for XT4, and the KXT2LTC-3 low terminal covers are a two-piece set for three-pole XT2. Whichever line you standardize on, the accessory has to match that manufacturer's frame.
11) Is the Square D S37423 kit RoHS compliant and mercury free?
Yes on both counts. The kit is RoHS (Europe) compliant with exemptions, mercury free, and carries China RoHS regulation label 7. It is made in the United States by Schneider Electric.
