Product FAQs
6 answersWhat does the -1212 suffix indicate on the LAL36350-1212 catalog number?
The -1212 suffix designates a factory-installed 1A/1B auxiliary switch. This provides one normally open and one normally closed contact for remote breaker status signaling.
What are the conductor capacity limits for the standard lugs on this 350A breaker?
The standard feed-thru lugs accommodate either a single 1 AWG to 600 kcmil conductor or dual 1 AWG to 250 kcmil conductors per phase. They are dual-rated for both copper and aluminum wiring.
How is the thermal magnetic trip unit configured on the LAL36350-1212?
It utilizes a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing you to tune the instantaneous short circuit trip threshold to your specific load requirements.
Is the LAL36350-1212 an I-Line or unit-mount breaker?
This is a unit-mount breaker designed for feed-thru wiring. It is typically installed in traditional switchboards, panelboards, and motor control centers rather than plug-on I-Line panels.
Does this Square D L-Frame breaker support direct current applications?
Yes, it is rated for DC systems up to 250VDC with a 10kAIC interrupting rating, making it suitable for specific industrial DC control or battery setups.
What breaker family does the LAL36350-1212 belong to?
It is part of the Square D legacy L-Frame molded case circuit breaker family, which is widely used in older Schneider Electric and Square D distribution equipment.
