Product FAQs
8 answersWhat type of panelboards is the LGA36400CU33X compatible with?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection and requires 6 inches of available I-Line mounting space.
Can I use the LGA36400CU33X in a standard unit-mount application?
No, the LGA frame is specifically built with an I-Line plug-in bracket for I-Line distribution panels. For unit-mount applications, you would need an LGL frame breaker.
What does the C in the LGA36400CU33X catalog number signify?
The C indicates that this circuit breaker is 100 percent rated for continuous application at its full 400A capacity. This requires installation in a properly sized enclosure using 90 degrees Celsius rated wire.
What type of trip unit is included with the LGA36400CU33X?
It includes a Micrologic 3.3 S electronic trip unit, designated by the U33X suffix. This provides adjustable Long-time, Short-time, and Instantaneous (LSI) protection settings.
What lug kit is installed on the load side of the LGA36400CU33X?
This I-Line breaker comes standard with AL600LS52K3 mechanical lugs on the load side. These lugs accept two 2/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What is the recommended tightening torque for the load-side lugs?
The AL600LS52K3 load lugs should be torqued to 442.5 lb-in (50 N.m) for secure and safe electrical connections.
How does the LGA36400CU33X differ from LJA or LLA models?
The second letter indicates the interrupting rating. The LGA has a G rating (35kA at 480VAC), while the LJA has a J rating (65kA at 480VAC) and the LLA has an L rating (100kA at 480VAC).
What local signaling indicators are on the Micrologic 3.3 S trip unit?
The trip unit features local LED signaling, including a green ready LED, an orange alarm LED indicating 90 percent Ir, and a red alarm LED indicating 105 percent Ir. These indicators help personnel monitor load conditions and prevent unexpected overloads.
