Product FAQs
6 answersWhat does the "SA" suffix indicate in the JJL36250SA catalog number?
The "SA" suffix designates that this PowerPacT J-Frame circuit breaker is factory-equipped with a 120VAC shunt trip accessory, allowing the breaker to be tripped remotely.
What is the difference between this unit-mount JJL36250SA and an I-Line breaker?
As a unit-mount (feed-thru) breaker, the JJL36250SA secures directly to a backpan or mounting surface and uses wire lugs on both the line and load sides. In contrast, I-Line breakers plug directly into a specialized busbar system on the line side.
Can the JJL36250SA be used to replace older Square D J-Frame breakers?
Yes, the JJL36250SA is part of the Square D PowerPacT J-Frame family and can often replace older or obsolete J-Frame breakers in existing switchboards and motor control centers, provided the enclosure supports unit-mount configurations.
What does the "L" in the JJL36250SA catalog number indicate?
In Square D PowerPacT nomenclature, the "L" designates that the breaker is configured with factory-installed lugs on both the line and load sides for unit mounting.
Does the JJL36250SA include a manual testing feature?
Yes, all PowerPacT J-Frame circuit breakers feature an integral push-to-trip button on the front cover, allowing operators to manually trip the breaker for testing and maintenance.
Is the JJL36250SA suitable for reverse-fed applications?
Yes, standard thermal-magnetic PowerPacT J-Frame circuit breakers like the JJL36250SA can be reverse-fed, as they do not have line and load side restrictions.
