Description
Built for industrial power distribution, the Square D LAL36250 delivers 250A of thermal-magnetic protection. This L-Frame MCCB handles demanding commercial loads with long-time and instantaneous (LI) trip functions. The three-pole unit mount breaker installs into Square D switchboards and motor control centers. The modern LGL36250 replacement has a lower 18kAIC rating at 600V, making this original LAL model highly valuable. Rated at 42kAIC at 240VAC, it features an adjustable magnetic trip.Specifications

Product FAQs
5 answersWhat are the adjustable magnetic trip settings for the LAL36250?
The magnetic trip unit on this 250A breaker is adjustable, featuring a low setting of 1250A and a high setting of 2500A.
What is the modern Square D replacement for the legacy LAL36250?
Square D has transitioned the legacy L-frame series to the newer PowerPact family. Facilities looking to modernize can upgrade to a 250A PowerPact J-frame circuit breaker, such as the JDL or JGL series, depending on the specific interrupting capacity required by the system.
Which standard lug kit is used on the LAL36250 circuit breaker?
This breaker typically comes equipped with AL400LA mechanical lugs. These terminals are rated to accept either a single 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors, and are compatible with both aluminum and copper wiring.
What is the difference between Square D LAL and LHL circuit breakers?
Both are legacy Square D L-frame breakers with the same physical footprint, but the LHL series is engineered for higher short-circuit interrupting ratings. If a panel calculation requires greater fault current capacity than the LAL36250 provides, the LHL36250 is the direct alternative.
Does the LAL frame include a manual test feature?
Yes, Square D LAL frame circuit breakers are equipped with a Push-to-Trip button. This allows electricians to safely verify the mechanical operation of the tripping mechanism during routine maintenance without exposing personnel to live electrical components.
