Product FAQs
7 answersWhat panelboards are compatible with the LXI36600G?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It cannot be installed in standard QO, NQ, or NF distribution panels.
Can I use this breaker in a standard unit-mount or bolt-on application?
No, the LXI36600G features an I-Line style plug-in connection on the line side and is specifically designed to mount onto an I-Line bus stack.
What does the G in the LXI36600G catalog number indicate?
The G signifies that the electronic trip unit includes Ground-Fault protection. This completes the LSIG (Long-Time, Short-Time, Instantaneous, Ground-Fault) suite of adjustable trip functions.
Is the Square D LXI36600G still in active production?
The LXI frame is a legacy molded case circuit breaker. Square D has transitioned this product line to the modern PowerPact L-frame series.
What is the modern replacement for the LXI36600G?
The direct modern equivalent is the PowerPact LLA36600U44X, which is a 600A L-frame breaker with an I-Line mounting configuration and a Micrologic LSIG trip unit.
How are the line and load connections configured on this breaker?
The line side utilizes Square D's I-Line plug-on jaws that connect directly to the panel's busbar stack. The load side features mechanical lugs that accept two cables per phase, ranging from 2/0 AWG to 500 kcmil for aluminum or copper conductors.
How does the electronic trip unit improve system coordination?
The solid-state electronic trip unit provides fully adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) settings. This allows electricians to precisely coordinate the breaker's trip curve with downstream protective devices.
