Product FAQs

8 answers
What type of panelboards are compatible with the LX36100?

This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection for quick installation onto the bus assembly.

Can I use this breaker in a standard QO or Homeline load center?

No. The LX36100 features an I-Line plug-in mounting style and is strictly compatible with commercial I-Line panelboards and switchboards. It will not fit in residential QO or Homeline enclosures.

What wire sizes and materials are accepted by the lugs on this breaker?

The terminal lugs accept either one 1 AWG to 600 kcmil conductor, or two 1 AWG to 250 kcmil conductors. Both aluminum and copper wire are supported.

What does the LSI designation mean on the LX36100 trip unit?

LSI indicates the electronic trip unit includes adjustable Long-time, Short-time, and Instantaneous protection functions. This allows for precise coordination with other breakers in your electrical system.

How does the electronic trip unit differ from a standard thermal-magnetic breaker?

Unlike fixed thermal-magnetic breakers, the electronic trip unit on this model provides adjustable trip settings. This delivers higher accuracy and better repeatability for complex commercial or industrial loads.

Is the LX36100 a current production model?

The LX frame is classified as a legacy molded case circuit breaker. While it is no longer the primary active series, it remains a direct replacement for existing I-Line installations requiring a 100A LX frame.

Does this breaker require a separate mounting hardware kit?

No, the I-Line plug-in connection design means the breaker snaps directly into the bus assembly of an I-Line panelboard without requiring separate bolt-on mounting kits.

What precautions should be taken before installing this I-Line breaker?

Installation should only be performed by a qualified electrician. Ensure the panelboard is fully de-energized before attempting to seat the plug-in jaws onto the busbars to prevent arc flash hazards.
