Description
Operating within the legacy L-Frame series, this 600A MCCB provides essential current-limiting capabilities. It utilizes a thermal-magnetic trip unit with fixed long-time and adjustable magnetic (LI) settings. The breaker mounts into standard Square D motor control centers and switchboards. Facilities transitioning to newer technology can substitute this unit with the LJL36600U31X. With a 65kAIC rating at 480V, it effectively isolates severe electrical faults.Specifications

Product FAQs
6 answersWhat is the difference between the Square D LAL, LHL, and LCL circuit breakers?
All three are L-Frame molded case circuit breakers with identical physical dimensions and mounting, but they differ in their interrupting capacity. The LAL is the standard interrupting version, the LHL is the high interrupting version, and the LCL provides extra-high interrupting capacity, rated up to 100kA at 240V and 65kA at 480V.
What wire size and material can be used with the lugs on the LCL36600?
The standard lugs on this breaker accept two cables per phase. They are rated for 2/0 AWG to 500 kcmil copper or aluminum wire.
Is the LCL36600 an I-Line plug-on breaker?
No, the LCL36600 is a unit-mount, bolt-on circuit breaker. It is designed for use in standard Square D switchboards, motor control centers, and individual enclosures. The I-Line plug-on equivalent for panelboards is the LIL36600.
How does the trip unit function on the LCL36600?
This breaker features a thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal element provides fixed overload protection at 600 amps, while the magnetic instantaneous trip is adjustable, allowing you to coordinate short-circuit protection with other devices in your electrical system.
What enclosures and equipment are compatible with the LCL36600?
As a unit-mount breaker, it is designed to bolt directly into Square D switchboards, motor control centers, and standalone industrial enclosures. It requires the appropriate mounting hardware and bus connections for the specific equipment.
What does the LI designation mean for the LCL36600 trip unit?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) and Instantaneous (I) protection. Long-Time protects against sustained overloads, while Instantaneous provides immediate tripping during severe short circuits.
