Description
A robust solution for heavy-duty systems, the LIL36350 is a 3-pole, 350A MCCB from Square D. It mounts into industrial switchboards and motor control centers. This legacy L-Frame device features lug terminals for (2) 2/0 AWG to 500 kcmil conductors. The LRL36400U31X is the recommended replacement when adjusted to 350A. Offering exceptional current-limiting capabilities, it boasts a 200kAIC rating at 480VAC. It provides LI protection via a fixed thermal and adjustable magnetic trip.Specifications

Product FAQs
6 answersWhat types of equipment is the Square D LIL36350 designed to be installed in?
This legacy L-Frame circuit breaker is designed for use in Square D switchboards, motor control centers, and industrial enclosures.
What wire sizes are accepted by the lugs on the LIL36350?
The factory lugs accept two aluminum or copper conductors ranging from 2/0 AWG to 500 kcmil per phase.
How does the LIL36350 mount into an electrical system?
It is a unit mount, feed-thru circuit breaker. This means it bolts directly to the mounting surface and uses lug connections for both the line and load sides, rather than plugging onto a busbar.
What does the LI trip function indicate on this breaker?
The LI designation means the thermal magnetic trip unit provides Long-Time (fixed thermal) and Instantaneous (adjustable magnetic) overcurrent protection.
How does the interrupting capacity of the LIL36350 change based on system voltage?
This current limiting breaker provides a high interrupting rating of 200kA at 240VAC and 480VAC, which drops to 100kA when applied to 600VAC systems.
Is the LIL36350 a current production model?
No, the LIL36350 is a legacy molded case circuit breaker. For modern upgrades or new installations, it is typically replaced by a comparable Square D PowerPact L-Frame circuit breaker configured for 350 amps.
