Square D MHL36500 – 500A 3 Pole Molded Case Circuit Breaker Clearance

Engineered for heavy-duty industrial applications, the MHL36500 is a 500A, 3-pole MCCB from Square D’s legacy M-Frame series. This unit-mount breaker installs into compatible switchboards, motor control centers, and enclosures. It serves as a direct replacement for aging M-Frame installations, though Square D has officially replaced this series with the PowerPact MJL36500. It features a thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions.
