Product FAQs
7 answersCan the MJL36600 be used to replace older Square D legacy breakers?
Yes, the PowerPacT M-Frame MJL36600 serves as a modern unit-mount replacement for legacy 600A Square D MA, MH, ME, and MX frame circuit breakers, such as the MA36600 and MH36600.
What type of trip unit is installed in the MJL36600?
This breaker features a basic ET 1.0 electronic trip unit. It provides fixed long-time protection and adjustable instantaneous protection, offering greater accuracy than standard thermal-magnetic trip units.
Are the trip unit settings on the MJL36600 field-replaceable or fully adjustable?
No, the ET 1.0 trip unit cannot be field-replaced. It features a fixed long-time trip point, though the instantaneous protection can be adjusted from 2 to 10 times the nominal ampere rating.
What type of enclosures or equipment is this breaker designed for?
The MJL36600 is a unit-mount breaker designed for installation in Square D switchboards, motor control centers (MCCs), and industrial control panels.
What does the "J" in the MJL36600 part number indicate?
The "J" designates the specific interrupting capacity tier within the Square D PowerPacT M-Frame family, which provides 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
Does this breaker come with line and load lugs?
Yes, the MJL36600 includes factory-installed box lugs on both the line and load sides. The terminals accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Does the MJL36600 include a manual trip feature for testing?
Yes, all Square D PowerPacT circuit breakers feature an integral push-to-trip button on the cover to manually trip the breaker and verify the mechanical operation of the trip mechanism.
