Product FAQs
7 answersWhat panels are compatible with the Square D LC36350?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on jaw connection to mount directly to the internal bus.
What is the modern replacement for the legacy LC36350?
For facilities looking to upgrade, this legacy L-Frame breaker can typically be replaced by the modern PowerPact L-Frame series, such as the LJA36400U31X, which mounts into the same I-Line panelboards.
What are the wire size limits for the lugs on this 350A breaker?
The factory lugs accept two conductors per phase, allowing you to run parallel cables. The terminals accept either aluminum or copper wire sized from 4/0 AWG to 500 kcmil.
Are the trip settings adjustable on this legacy LC frame breaker?
The long-time thermal trip is fixed at 350 amps, but the instantaneous magnetic trip is adjustable. This allows you to fine-tune the short-circuit response to achieve better coordination with other protective devices in your system.
Can this breaker be used in DC systems?
Yes. In addition to its AC ratings, this unit is certified for 250VDC applications with a 10kA interrupting capacity, making it suitable for specialized industrial DC power distribution.
Do I need separate busbar hardware to install this breaker?
No. The breaker features an integrated I-Line jaw connection that pushes directly onto the panelboard bus assembly. This eliminates the need for separate bolt-on bus hardware, streamlining the installation.
Is the LC36350 circuit breaker HACR rated?
Yes, this model carries an HACR rating, meaning it is certified for group motor installations in heating, air conditioning, and refrigeration equipment. It also meets standard UL 489 requirements for molded case circuit breakers.
