Product FAQs
6 answersWhat type of panels or switchboards can accommodate the LGP36400U33X?
This unit-mount PowerPacT L-frame breaker is designed for use in Square D QED switchboards, custom control panels, and standalone industrial enclosures. It is not compatible with I-Line panelboards, which require a plug-on bracket.
Can I mount the LGP36400U33X in an I-Line panelboard?
No, the LGP36400U33X is a unit-mount circuit breaker designed for bolt-on installations. If you need a breaker for an I-Line panelboard, you must use the I-Line version, catalog number LGA36400U33X, which includes the required plug-on bracket.
What protection features does the Micrologic 3.3S trip unit provide on this breaker?
The "U33X" suffix denotes a Micrologic 3.3S electronic trip unit, which delivers LSI (Long-time, Short-time, and Instantaneous) protection. These adjustable settings allow electricians to fine-tune the trip curve for precise system coordination and selective coordination requirements.
What does the "G" in the LGP36400U33X part number indicate?
The "G" indicates the breaker's interrupting rating tier within the PowerPacT L-frame series. It signifies a maximum interrupting capacity of 65kA at 240V, 35kA at 480V, and 18kA at 600V.
How do I connect the wiring to the LGP36400U33X?
The breaker comes with factory-installed mechanical lugs designed for bolt-on, unit-mount installations. Each lug accommodates two aluminum or copper conductors ranging from 2/0 AWG to 500 kcmil. Ensure proper torque specifications are followed during installation as outlined by Schneider Electric.
Does the LGP36400U33X include ground fault protection?
No, the Micrologic 3.3S trip unit provides LSI (Long-time, Short-time, and Instantaneous) protection only. If your application requires equipment ground fault protection, you will need a breaker equipped with an LSIG trip unit.
