Product FAQs
8 answersWhat does the 1021 suffix mean on the LAL362501021?
The 1021 suffix indicates that this breaker includes a factory-installed 120/240VAC shunt trip. This allows the breaker to be tripped remotely by an external control signal.
Can I install the LAL362501021 in a Square D I-Line panelboard?
No, the LAL362501021 is a unit-mount (feed-thru) breaker designed for industrial enclosures, switchboards, and motor control centers. For I-Line panelboards, you need the I-Line equivalent, which is the LA36250.
Which Square D enclosures are compatible with the LAL362501021?
This L-frame breaker mounts in Square D 400A circuit breaker enclosures, including the LA400S (NEMA 1 surface mount), LA400F (NEMA 1 flush mount), LA400R (NEMA 3R), and LA400AWK (NEMA 12).
What is the DC voltage rating for the LAL362501021?
This breaker is rated for up to 250VDC, with a DC interrupting rating of 10kAIC.
What is the interrupting capacity of this breaker on a 240V system?
While rated for 30kAIC at 480V, the LAL362501021 has a higher interrupting rating of 42kAIC when used on 240VAC systems.
Is the trip unit on the LAL362501021 fully adjustable?
No, this thermal-magnetic breaker has a fixed thermal trip for overload protection, but it features an adjustable magnetic trip for short-circuit protection.
Can I manually trip the LAL362501021 for maintenance?
Yes, this breaker features a Push-to-Trip button that allows you to manually open the circuit and test the mechanical linkage without exposing yourself to live parts.
Is the LAL362501021 still in active production?
The LAL series is a legacy molded case circuit breaker frame. While still widely used in existing switchboards and motor control centers, Schneider Electric has transitioned to the PowerPact series for new installations.
