Description
A reliable solution for commercial facilities, the LHL36200 is a 200A, 3-pole MCCB. It belongs to Square D's legacy L-Frame family, providing essential overcurrent safety. The unit mount design allows for secure installation into Square D switchboards. When replacing this model, the JGL36200 is the substitute, requiring a frame change. It features a thermal-magnetic trip mechanism with adjustable magnetic (LI) settings. The breaker is rated 35 kAIC at 480VAC and is HACR certified.Specifications

Product FAQs
5 answersWhat is the wire range and torque specification for the LHL36200 lugs?
The LHL36200 accepts either one 1 AWG to 600 kcmil or two 1 AWG to 250 kcmil aluminum or copper wires. The required tightening torque for the lugs is 115 lb-in (13 N.m).
Is the Square D LHL36200 obsolete, and what is the direct replacement?
The LHL36200 is a legacy L-frame breaker. The modern equivalent is the PowerPact J-frame, specifically the JGL36200. Note that upgrading to the J-frame requires a frame change, as the physical dimensions and mounting footprints differ.
How do you adjust the trip settings on the LHL36200?
This thermal-magnetic breaker features a fixed thermal overload and an adjustable magnetic instantaneous trip. The magnetic trip can be adjusted between 1000A and 2000A using the dial on the front of the breaker to accommodate inrush currents or coordinate with downstream devices.
Can the LHL36200 be used in DC applications?
Yes, the LHL36200 is rated for use in DC systems up to 250VDC, where it provides an interrupting rating of 50 kAIC.
What type of enclosures are compatible with the LHL36200?
The LHL36200 is designed for unit mount installation in Square D legacy L-frame enclosures, switchboards, and panelboards. It is compatible with NEMA 1, 3R, 4, 4X, 5, and 12 rated L-frame enclosures.
