Product FAQs
8 answersWhat panels are compatible with the LE36200LS circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the busbar stack.
What does the LS designation mean on the LE36200LS trip unit?
The LS designates the electronic trip functions included in the Micrologic trip unit. It stands for Long-Time and Short-Time, which allows for adjustable overcurrent protection and system coordination.
What wire sizes are accepted by the lugs on the LE36200LS?
The standard lugs on this breaker accept 2 AWG to 500 kcmil aluminum wire or 2 AWG to 600 kcmil copper wire.
What is the modern replacement for the legacy LE36200LS breaker?
The LE frame is a legacy molded case circuit breaker. It is typically superseded by the newer PowerPact L-frame series, such as the LLA36250U33X, which requires an HNM1BL blank filler plate when retrofitting into older I-Line panels.
How is the LE36200LS secured to the I-Line panelboard?
The breaker features plug-on jaws that attach directly to the I-Line busbar stack. It is then secured with a retaining screw through the mounting bracket into the panel pan to prevent movement.
What is the maximum fault current the LE36200LS can safely interrupt at 480VAC?
This breaker has a high interrupting capacity of 65kAIC at 480VAC, making it suitable for commercial and industrial systems with substantial available fault current.
Can the LE36200LS be used in 600V systems?
Yes, this breaker is rated for up to 600VAC. At 600V, it provides an interrupting capacity of 35kAIC.
Does the LE36200LS support interchangeable trip units?
No, this specific breaker features a non-interchangeable Micrologic Series B electronic trip unit.
