Square D MAL36800 Molded Case Circuit Breaker

No. The MAL36800 is a unit mount, feed-thru circuit breaker designed to be hardwired via lugs in switchboards, motor control centers, and standalone enclosures. For I-Line panelboards, you will need the appropriate plug-on I-Line equivalent.

The factory AL900MA mechanical lugs included with the MAL36800 accept up to three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase. Always verify terminal torque requirements on the lug labeling prior to energizing.

The instantaneous magnetic trip is field adjustable. On the 800A MAL frame, the magnetic trip settings range from a low setting of 4000A to a high setting of 8000A to coordinate with your system short circuit protection needs.

The MAL series is part of the legacy M-Frame family. For new installations or system upgrades requiring an 800A unit mount breaker, the current replacement is typically the Square D PowerPact M-Frame, such as the MGL36800, which features upgraded electronic trip units.

Yes. While it is commonly used for standard alternating current distribution, the MAL36800 thermal magnetic breaker is also rated for up to 250VDC with a 14kA interrupting capacity, making it suitable for direct current backup and control applications.

No. As a unit mount or feed-thru breaker, it mounts directly to the backpan of an enclosure or switchboard using standard hardware, without requiring a plug-in base or drawout cradle.

Yes. The MAL36800 is HACR rated, meaning it has been tested and certified to safely handle the specific inrush currents and continuous loads associated with commercial heating, air conditioning, and refrigeration systems.

No. The thermal or long-time trip function is fixed at 800A. Only the magnetic or instantaneous trip threshold can be manually adjusted on this specific thermal magnetic circuit breaker.
