Product FAQs
6 answersWhat wire sizes and materials are compatible with the MHL36700 lugs?
The standard lugs accept three conductors per phase, ranging from 3/0 AWG to 500 kcmil. They are rated for both aluminum and copper wiring.
What type of equipment is the MHL36700 designed to be installed in?
This unit-mount, feed-thru circuit breaker is designed for direct installation into Square D switchboards and motor control centers (MCCs). It does not snap into standard panelboards.
How does the trip unit function on this 700A breaker?
It features a thermal-magnetic trip unit with a fixed thermal overload setting of 700A and an adjustable magnetic (instantaneous) setting. This adjustability allows electricians to coordinate the breaker with downstream devices or handle specific motor inrush currents.
Is the MHL36700 still in active production, or is there a direct replacement?
The MHL36700 is part of Square D's legacy M-Frame series. When a replacement is needed for new installations or upgrades, the newer PowerPact MJL36700 model is typically used as a substitute.
Can the MHL36700 be used in DC power systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, where it provides a 50kA interrupting capacity.
What is the catalog number for the replacement lug kit for this breaker?
The standard mechanical lug kit for the MHL36700 is catalog number AL900MA. Note that these are typically supplied as one lug per kit, so multiple kits may be required to fully terminate the line and load sides.
