Description
Engineered for commercial and industrial applications, the Square D LAL26250 is a 2-pole, 250A molded case circuit breaker providing Long-Time and Instantaneous (LI) protection. This unit-mount breaker installs into standard industrial enclosures and switchboards. As a legacy LA-Frame component, it is replaced by the LGL36250 (using outer poles) for system upgrades. It features an adjustable magnetic trip, HACR rating, and a 42kAIC capacity at 240VAC, complete with factory lugs.Specifications

Product FAQs
7 answersWhat wire sizes are accepted by the standard lugs on the LAL26250?
The standard mechanical lugs on this breaker accept either one 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors per phase. Both aluminum and copper wires are supported.
How is the LAL26250 mounted in a panel?
The LAL26250 is a unit-mount, feed-thru breaker. It bolts directly to the mounting pan or enclosure and uses mechanical lugs for both line and load connections, rather than plugging into a busbar. It is commonly used in industrial enclosures, switchboards, and motor control centers.
What is the adjustable magnetic trip range for the LAL26250?
The LAL26250 features an adjustable magnetic trip that can be set between 1250A (Low) and 2500A (High). This allows for precise coordination with downstream loads for instantaneous short-circuit protection.
Can this 2-pole breaker be used in a 3-phase system?
Yes, a 2-pole breaker like the LAL26250 can be installed in a 3-phase panel or switchboard to feed single-phase loads, provided the enclosure accepts unit-mount L-Frame breakers. It will occupy two phases of the system.
Is the LAL26250 rated for DC applications?
Yes, the LAL26250 is rated for up to 250VDC with an interrupting capacity of 10kAIC. This makes it suitable for specific industrial DC control circuits and battery systems.
What is the difference between the LAL26250 and the LHL26250?
The LAL26250 is the standard interrupting version, rated at 30kAIC at 480VAC. The LHL26250 is the high-interrupting version, rated at 35kAIC at 480VAC and 65kAIC at 240VAC. Both share the same physical dimensions, mounting, and trip units.
What is the modern replacement for the legacy LAL26250?
The LAL26250 is a legacy L-Frame breaker. For modern system upgrades, it is typically replaced by the PowerPact L-Frame series, such as the LGL36250, using the outer poles for 2-pole applications. Note that PowerPact breakers have different dimensions and mounting requirements, so retrofitting may require panel modifications or adapter hardware.
