Product FAQs
6 answersWhat legacy Square D circuit breaker does the JJL36225AALC replace?
This PowerPacT J-Frame breaker serves as a direct replacement for discontinued KH36225 components. It provides an upgraded thermal-magnetic trip unit while maintaining compatibility with existing heavy-duty systems.
What do the AA and LC suffixes indicate on the JJL36225AALC catalog number?
The AA suffix indicates the breaker includes one factory-installed 1a1b auxiliary switch for remote status signaling. The LC suffix specifies that the unit is equipped with copper mechanical lugs on both the line and load sides.
What enclosures and panels are compatible with this J-Frame breaker?
This unit-mount breaker is designed for installation in Square D J-Frame enclosures, switchboards, and motor control centers. It features a feed-thru connection and mounts directly using the provided lugs.
How does the adjustable magnetic trip function work on this 225A breaker?
While the thermal protection is fixed at 225 amps for long-time overloads, the magnetic trip is adjustable. This allows electricians to fine-tune the instantaneous short-circuit response to match specific load characteristics and coordination requirements.
What wire sizes and materials are accepted by the factory-installed lugs?
The copper mechanical lugs accept copper wire only, ranging from 1/0 AWG to 300 kcmil. Ensure proper torque specifications are followed during installation for secure connections.
Can the JJL36225AALC be reverse fed?
Yes, this thermal-magnetic breaker features a reverse-feed capable design. This allows the line and load connections to be swapped if required by the specific panel layout or wiring configuration.
