Product FAQs
7 answersWhat panelboards accept the LA362501212 circuit breaker?
This breaker features an I-Line plug-on design and is exclusively compatible with Square D I-Line distribution panelboards and switchboards. It will not fit in standard load centers or NQ/NF panels.
How much mounting space does this LA frame breaker require in an I-Line panel?
The 3-pole LA frame I-Line circuit breaker requires 6 inches of mounting space on the panel bus.
What does the 1212 suffix mean on the LA362501212 catalog number?
The 1212 suffix indicates that this breaker includes a factory-installed auxiliary switch with 1A/1B (one normally open and one normally closed) contacts. This is typically used for remote signaling and control circuits.
What wire sizes are accepted by the standard lugs on the LA362501212?
The standard lugs accept either a single 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors. The terminals are rated for both aluminum and copper (Al/Cu) wiring.
Is there a modern replacement for the legacy LA362501212 breaker?
The LA series is a legacy frame. Facilities looking to modernize can transition to the newer Square D PowerPacT series, such as the J-frame (e.g., JJA36250) or L-frame equivalents, which offer updated trip units while maintaining I-Line bus compatibility.
Are the trip settings adjustable on this thermal-magnetic breaker?
Yes, the LA362501212 features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Can the LA362501212 be used in DC electrical systems?
Yes, this breaker is rated for use in DC circuits up to 250VDC, providing a maximum interrupting capacity of 10kA at that voltage.
