Description
Serving as a high-capacity protection device, the Square D MAL36500 is a 3-pole, 500A molded case circuit breaker. It is engineered to safeguard heavy commercial circuits against overloads and short circuits. This unit mount MCCB integrates into Square D switchboards, motor control centers, and enclosures. As a legacy M-Frame component, it is replaced by the PowerPact MGL36500 for newer installations. The breaker utilizes thermal-magnetic trip technology, offering a 42kAIC rating at 240VAC.Specifications

Product FAQs
6 answersIs the Square D MAL36500 circuit breaker still manufactured?
The MAL36500 is an obsolete legacy M-frame breaker. For new installations or system upgrades, Schneider Electric recommends replacing it with the PowerPact M-frame series, such as the MGL36500. Exact cross-references depend on the required fault current ratings and enclosure clearances.
What wire sizes do the factory lugs on the MAL36500 accept?
The standard AL900MA mechanical lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What is the adjustable magnetic trip range for this 500A breaker?
The instantaneous magnetic trip is adjustable from a low setting of 2500A to a high setting of 5000A. The thermal long-time trip function remains fixed at 500A.
Can the MAL36500 be installed in an I-Line panelboard?
No, this is a unit-mount, feed-thru circuit breaker designed for bolt-on installation in Square D switchboards, motor control centers, and individual enclosures. It lacks the plug-on jaw connections required for I-Line bussing.
Does the MAL36500 carry a DC voltage rating?
Yes. In addition to its AC ratings, this thermal-magnetic breaker is rated for 250VDC applications with an interrupting capacity of 14 kAIC.
Can I upgrade the MAL36500 with a Micrologic electronic trip unit?
No, the legacy MAL frame is strictly a thermal-magnetic circuit breaker. If advanced electronic trip functions like short-time or ground-fault protection are required, the circuit must be upgraded to a newer PowerPact M or P-frame breaker.
