Product FAQs

5 answers
What is the modern replacement for the legacy LC36600 circuit breaker?

Schneider Electric has superseded the LC36600 with the PowerPact L-frame LJA36600U31X. This newer model is a direct I-Line replacement but utilizes an advanced electronic MicroLogic trip unit instead of the older thermal-magnetic design.

What is the adjustable magnetic trip range for the LC36600?

The magnetic trip unit on this 600A breaker can be adjusted between a low setting of 3000A and a high setting of 4200A to accommodate varying inrush current requirements.

What replacement lug kit is required for the LC36600?

The standard mechanical lug kit for the LC36600 is the AL600LI5. These lugs accept two 4/0 AWG to 500 kcmil aluminum or copper conductors per phase.

Can the LC36600 be installed in standard NQ or NF distribution panels?

No. The LC36600 utilizes an I-Line plug-on connection and is exclusively compatible with Square D I-Line panelboards and switchboards. It will not fit in NQ or NF lighting panels.

Is the LC36600 considered a current-limiting circuit breaker?

No, the LC36600 provides extra-high interrupting capacity but is not formally rated as current-limiting. In the legacy Square D L-frame series, current-limiting performance requires the LI36600 (I-Limiter) model.
