Square D PowerPacT H/J/L Trip Unit Accessory, 110-130VAC

The Square D PowerPacT H/J/L Trip Unit Accessory is a circuit breaker accessory line that adds remote tripping capability to PowerPacT H, J, and L frame circuit breakers. Available in Shunt and Undervoltage trip types, these units are energized from a separate 110VAC to 130VAC voltage source, letting the breaker be tripped remotely from a location independent of the main circuit — giving panel builders and OEMs flexible design options for industrial and commercial power distribution. Both trip types terminate via spring clamp connections rated 0.82-2.5 mm² (AWG 18...AWG 14) at 1.4 N.m tightening torque, ship 100 per case, and are CSA certified and mercury-free.

Key Features

  • Remote Trip Capability: Shunt and Undervoltage trip options provide remote trip capability energized from a separate voltage circuit, independent of the main breaker circuit.
  • Voltage Rating: Requires 110VAC to 130VAC to energize the trip coils.
  • Spring Clamp Connection: Spring clamp connection for easy installation, rated 0.82-2.5 mm² (AWG 18...AWG 14) at 1.4 N.m tightening torque.
  • Compatible Range: Designed for the PowerPacT H, PowerPacT J, and PowerPacT L frame circuit breaker range.
  • Flexible Design: Part of the PowerPacT H/J/L accessory line, allowing flexible panel and switchgear design with either Shunt or Undervoltage trip function.
  • Standard Function Option: Factory-standard function option for straightforward specification.
  • Mercury Free Construction: Mercury-free build supports environmentally responsible installations.

Square D P29386 – Frequently Asked Questions

1) What is the difference between the shunt trip and undervoltage trip version of the Square D PowerPacT H/J/L trip unit?
Both add remote tripping to PowerPacT H, J, and L frame breakers, but they trip on opposite conditions. The shunt trip (P29386) opens the breaker when its coil is energized from the separate 110-130VAC control source, so it is used for remote push-button trip or safety shutdown circuits. The undervoltage trip (P29406) does the reverse: it holds the breaker closed while energized and trips it when that control voltage drops away, which is what you want for loss-of-voltage protection. Both are energized from a circuit independent of the main breaker circuit.
2) Will this trip unit fit my Square D PowerPacT breaker?
It is built for the PowerPacT H, J, and L frame breakers only. If your breaker is an H, J, or L frame PowerPacT, either the shunt or the undervoltage unit applies. Other PowerPacT frames and other breaker lines use different accessories, so confirm the frame letter on the breaker label before ordering.
3) What wire size can I land on the PowerPacT H/J/L trip unit terminals?
The terminals are spring clamp type and take 0.82 to 2.5 mm2 conductor, which is AWG 18 through AWG 14, at 1.4 N.m tightening torque. Spring clamp means no screw to torque on the conductor itself for normal field wiring, so control wiring lands quickly in a crowded panel.
4) Can I add remote trip to a PowerPacT breaker already installed in a panel?
Yes, these are field-installable accessories for existing PowerPacT H, J, and L frame breakers, and retrofits are one of the stated applications. You are adding the trip unit to the breaker and running a separate 110-130VAC control circuit to it. The trip stays independent of the main circuit, so the breaker's load-side wiring is untouched.
5) Which PowerPacT trip unit should I use for a remote emergency shutdown button?
Use the shunt trip, P29386. A momentary 110-130VAC signal to its coil trips the breaker, which is how a remote stop or safety shutdown circuit is normally built. The undervoltage unit (P29406) will not do that job, since it trips when control voltage is lost rather than when it is applied.
6) How does the Square D PowerPacT trip unit accessory ship, bulk or single?
Packaging is 100 each per case, so this is a case-quantity item aimed at panel builders and OEMs standardizing one trip function across a build. The function option is the factory Standard, so there is nothing further to specify beyond picking shunt or undervoltage.
