Built for heavy-duty power distribution, the Square D MAL36700 delivers 700A of thermal-magnetic protection. This 3-pole breaker features an adjustable magnetic trip for precise coordination and carries a 42kAIC rating at 240VAC. Designed with a unit-mount configuration and lug terminals, it integrates easily into Square D switchboards and motor control centers. For facility upgrades or maintenance, this legacy M-Frame component transitions to the modern MGL36700 equivalent when upgrading.
Is the MAL36700 still manufactured, or is there a modern replacement?
The MAL36700 is a legacy M-Frame circuit breaker. For new installations or facility upgrades, it transitions to the modern Square D PowerPact M-Frame series, such as the MGL36700, which offers updated electronic trip units while covering the same 700A footprint.
Can I install the MAL36700 in an I-Line panelboard?
No, the MAL36700 is a unit mount, or feed-thru, breaker designed for bolt-on installations. It uses cable lugs on both the line and load sides and lacks the required jaw connections to plug into an I-Line bussing system. You must use an I-Line specific breaker for those panelboards.
How is the magnetic trip adjusted on this breaker?
The MAL36700 features a thermal magnetic trip unit with a fixed thermal element and an adjustable magnetic element. The instantaneous magnetic trip threshold can be dialed in using the adjustment switch on the face of the breaker, allowing for precise coordination with downstream devices.
What wire sizes are compatible with the standard lugs on the MAL36700?
The factory lug configuration accepts three conductors per phase. It is compatible with both aluminum and copper wiring, accommodating wire gauges from 3/0 AWG up to 500 kcmil.
Where is the MAL36700 typically installed?
This 700A breaker is designed for heavy-duty power distribution and is commonly installed in Square D switchboards, motor control centers, and standalone industrial enclosures.
