Product FAQs
5 answersWhich electrical enclosures and switchboards accept the LEL36400LI?
This breaker is specifically rated for use within Square D QED Switchboards, Model 6 Motor Control Centers, and individual enclosures configured for legacy L-Frame breakers.
What wire configurations do the terminal lugs support?
The factory lugs can accommodate either one 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors per phase. They are dual-rated for both aluminum and copper wiring.
Can the LEL36400LI be installed directly onto an I-Line bus?
No. This model features a unit mount configuration. It is designed to be bolted into place and does not include the plug-on jaw connection required for I-Line panelboards.
What advantages does the LI electronic trip unit provide?
The LI designation indicates adjustable long-time and instantaneous protection. This solid state trip unit allows electricians to precisely tune the overload and short-circuit response curves to coordinate with other protective devices in the system.
Is the LEL series considered a current or legacy product line?
The LEL family is a legacy molded case circuit breaker. While it is commonly used as a direct drop-in replacement for existing gear, modern Schneider Electric installations typically utilize the newer PowerPact L-Frame series.
