Description

Rated for 100% continuous current, this 100A molded case circuit breaker features an advanced Micrologic trip unit. It provides adjustable long-time, short-time, instantaneous, and ground-fault (LSIG) protection. The unit mount design bolts into Square D QED switchboards, Model 6 MCCs, and enclosures. For modern replacements, use the PowerPact LJL36250U63X with the trip adjusted down to 100A. With 65kAIC at 480VAC, this HACR-rated breaker utilizes true RMS sensing for reliable operation.

Product FAQs

6 answers
What equipment is compatible with the LEL36100LSG circuit breaker?

This unit mount breaker is designed for use in Square D QED switchboards, Model 6 motor control centers, and individual enclosures.

What wire sizes do the terminals on the LEL36100LSG accept?

The included lugs accept either one 1 AWG to 600 kcmil aluminum or copper wire, or two 1 AWG to 250 kcmil aluminum or copper wires per phase.

What protection features are included in the LSIG electronic trip unit?

The LSIG designation indicates the electronic trip unit provides adjustable protection for Long-Time (overload), Short-Time (short circuit with intentional delay), Instantaneous (immediate short circuit), and Ground-Fault conditions.

Can I install the LEL36100LSG in an I-Line panelboard?

No. The LEL36100LSG is a unit mount, feed-thru circuit breaker. It is not equipped with the plug-on jaw connectors required for I-Line panelboards.

What is the difference between the LEL36100LSG and an LAL series breaker?

Both are L-frame circuit breakers, but the LEL series features a solid-state electronic trip unit for precise adjustability, whereas the LAL series uses standard thermal-magnetic trip technology.

What is the modern replacement for the legacy LEL36100LSG circuit breaker?

For a modern equivalent, you can use a PowerPact L-Frame breaker, such as the LJL36250U63X, with the electronic trip unit adjusted down to match the 100A requirement.
