Description
Operating as a crucial safety component, the Square D LAL36150 provides reliable thermal-magnetic protection for industrial power systems. This 3-pole, 150A breaker interrupts potentially damaging overcurrents. Equipped with a unit-mount configuration, it fastens easily into Square D enclosures. While the LGL36150 is often cited as a replacement, the LJL36150 is required to match the original 22 kAIC rating at 600V. This legacy MCCB supports 600VAC applications and is fully HACR rated.Specifications

Product FAQs
5 answersWhat wire sizes and materials are compatible with the standard lugs on the LAL36150?
The factory lugs accept either a single 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors per phase. The terminals are dual-rated for both aluminum and copper wiring.
What type of equipment is this unit-mount breaker designed for?
This feed-thru breaker is engineered for hardwired installations in Square D industrial enclosures, switchboards, and motor control centers rather than plug-on panelboards.
How does the trip adjustability work on this specific L-Frame breaker?
This thermal magnetic breaker features a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing you to dial in the instantaneous short-circuit trip threshold based on your load requirements.
Can the LAL36150 be used in direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for industrial DC control and distribution circuits.
Is the LAL36150 a direct replacement for older Square D L-frame breakers?
Yes, the LAL series is the standard legacy L-frame molded case circuit breaker. It serves as a direct replacement for older unit-mount L-frame breakers with matching 3-pole, 150A configurations.
