Product FAQs
5 answersWhat wire configuration is required for the MAL361000 terminal lugs?
The standard lugs require four separate 1/0 AWG to 350 kcmil aluminum or copper conductors per phase to safely distribute the 1000A load.
What panels or enclosures accept the MAL361000?
This unit-mounted breaker is designed for installation in Square D switchboards, motor control centers, and standalone enclosures. Because it is a feed-thru breaker, it cannot be installed in Square D I-Line panelboards, which require plug-on bus connections.
How does the thermal-magnetic trip unit function on this model?
It provides a fixed thermal trip for long-time overload protection and an adjustable magnetic trip dial, allowing electricians to tune the instantaneous short-circuit response based on specific application requirements.
Is the MAL361000 still the current standard for Square D 1000A breakers?
The MAL361000 is a legacy M-frame breaker commonly sourced to maintain and service existing equipment. For entirely new installations, Square D now standardizes on the PowerPacT P-frame series for 1000A applications.
How does the MAL361000 differ from the MHL361000?
Both are 1000A, 3-pole M-frame breakers, but they have different Ampere Interrupting Capacities (AIC). The MAL361000 is a standard-interrupting breaker rated at 30kAIC at 480V. The MHL361000 is a high-interrupting breaker rated at 65kAIC at 480V.
