Square D MA36700 Molded Case Circuit Breaker

The MA36700 has been discontinued and replaced by the Square D PowerPacT M-frame series. The recommended direct I-Line replacement is the MGA36700, which fits the exact same panel space but features an upgraded electronic trip unit.

This thermal-magnetic breaker has a fixed continuous current rating of 700A and an adjustable instantaneous magnetic trip. The magnetic trip dial can be set between a low of 3,500A and a high of 7,000A depending on your system coordination requirements.

This breaker requires 9 inches of vertical mounting space on the I-Line bus. The overall physical dimensions of the breaker frame are 9 inches wide, 6.5 inches deep, and 14 inches high.

The standard factory load-side lug kit is the AL900MA. Each phase terminal can accept three 3/0 AWG to 500 kcmil aluminum or copper conductors.

No separate hardware kit is required. As an I-Line style breaker, the MA36700 features factory-installed plug-on jaws on the line side that clamp directly onto the panelboard bus. Only the load side requires manual mechanical lug terminations.

This 3-pole breaker is factory configured for an ABC phase connection, allowing it to distribute power evenly across all three phases of a standard Square D I-Line panelboard.

Yes. If your electrical system requires a short-circuit rating greater than the standard 30kA at 480VAC, the MH36700 is the high-interrupting equivalent. It provides up to 65kA at 480VAC within the same physical frame size.

No. The MA36700 is exclusively designed for I-Line plug-on panels. If you need a unit-mount breaker with mechanical lugs on both the line and load sides for a standard enclosure or standalone configuration, you must use the MAL36700.
