Product FAQs
8 answersWhich panelboards are compatible with the LGA36400CU31X?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the busbar.
What wire sizes are accepted by the lugs on this breaker?
The factory-installed lugs accept two 2/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What does the C in the LGA36400CU31X catalog number indicate?
The C indicates that this breaker is 100% rated for continuous current, meaning it can carry its full 400A rating continuously without the standard 80% derating requirement.
What trip unit is included with the LGA36400CU31X?
This breaker includes a Micrologic 3.3 electronic trip unit, indicated by the U31X suffix. It provides adjustable long-time and instantaneous (LI) protection settings.
What does the G in the LGA prefix signify?
The G indicates the interrupting rating tier within the PowerPacT L-frame series, which provides 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Does this breaker require a separate mounting hardware kit?
No. As an I-Line plug-in breaker, it includes the necessary jaw connections to attach directly to the I-Line busbar without separate mounting brackets.
Can I use this breaker in a standard QO or NQ panel?
No. This is an L-frame I-Line breaker and will only fit I-Line distribution panels and switchboards. It is not compatible with QO, NQ, or NF series panelboards.
