Description
Engineered for heavy-duty industrial applications, the Square D LAL363501027 delivers reliable thermal-magnetic protection. This 3-pole, 350A breaker handles demanding electrical loads. It installs into standard enclosures, switchboards, and motor control centers via a unit-mount configuration. As a legacy L-Frame component, it is replaced by the modern LGL36350 (requires S29407 undervoltage release). Rated 30 kAIC at 480V, it features a factory-installed undervoltage release.Specifications

Product FAQs
6 answersWhat does the 1027 suffix indicate on the LAL363501027?
The 1027 suffix means this breaker includes a factory-installed 24VDC shunt trip (accessory part number LA11027). This allows the breaker to be tripped remotely via a 24VDC control signal.
What type of lugs are included with this 350A breaker?
This breaker uses standard AL400LA mechanical lugs on both the line and load sides. These lugs accept either one 1 AWG to 600 kcmil wire or two 1 AWG to 250 kcmil wires (aluminum or copper).
Is the LAL363501027 designed for I-Line panelboards?
No. The LAL series features a unit mount design for use in individual enclosures, switchboards, and motor control centers. It is not compatible with I-Line plug-on panelboards.
What is the difference between the Square D LAL and LHL series?
The primary difference is the interrupting capacity. The LAL series is the standard-rated version (30kA at 480VAC), while the LHL series is the higher-interrupting version (35kA at 480VAC). Both share the same physical footprint and L-frame design.
What is the modern equivalent to this legacy L-frame breaker?
The legacy LAL series is commonly replaced by the newer Square D PowerPact L-frame series, such as the LGL36350 (when equipped with a 24VDC shunt trip). Always verify that the new breaker's dimensions and AIC ratings meet your specific panel requirements before upgrading.
Can the magnetic trip setting be adjusted on this breaker?
Yes, this thermal-magnetic breaker features a fixed thermal element for overload protection and an adjustable magnetic trip element for short-circuit protection.
