Description
Designed for advanced control schemes, this 225A thermal-magnetic breaker includes a factory-installed 120/240VAC shunt trip mechanism for remote actuation. It integrates smoothly into Square D switchboards, panelboards, and motor control centers requiring automated disconnect capabilities. The L-Frame footprint ensures compatibility with existing legacy infrastructure while delivering 30kAIC interrupt capacity at 480V. When upgrading, engineers typically specify the PowerPacT LJL36225.Specifications

Product FAQs
8 answersWhat does the 1021 suffix mean on the LAL362251021 circuit breaker?
The 1021 suffix indicates that this breaker includes a factory-installed 120 to 240VAC shunt trip. This accessory allows the breaker to be tripped remotely by applying voltage to the shunt trip coil.
Which panelboards and switchboards are compatible with the LAL362251021 breaker?
This L-Frame breaker is designed for use in Square D panelboards, switchboards, and motor control centers that accept unit-mount LA or LAL frame breakers. It is not compatible with I-Line plug-on panels, which require an I-Line specific breaker.
How is the LAL362251021 mounted in an electrical enclosure?
This is a unit-mount circuit breaker, meaning it bolts directly to the mounting pan or backplate of the enclosure and connects to the bus or cables using feed-thru lugs.
Can the LAL362251021 be used in DC applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC, making it suitable for specific direct current systems.
What size wire can be used with the lugs on the LAL362251021?
The factory lugs accept either one 1 AWG to 600 kcmil aluminum or copper wire, or two 1 AWG to 250 kcmil aluminum or copper wires per phase.
Is the trip unit on the LAL362251021 adjustable?
The thermal long-time trip function is fixed at 225 amps, but the magnetic instantaneous trip function is adjustable to allow coordination with other protective devices in your system.
How should the shunt trip on the LAL362251021 be wired for safe operation?
The shunt trip coil must be wired to a separate control power source of 120 to 240VAC. When a remote switch or relay closes the circuit, the coil energizes and mechanically trips the breaker to open the main contacts.
What is the difference between an LA and LAL frame breaker?
The LAL is the standard interrupting capacity version of the legacy LA frame. They share the same physical dimensions and mounting footprint, allowing them to be used in enclosures designed for unit-mount L-Frame breakers.
