Product FAQs
7 answersWhat does the "1" at the end of the QJA222001 catalog number signify?
The "1" indicates that this 2-pole I-Line circuit breaker is factory-configured for an AB phase connection on the panelboard bus.
Can the QJA222001 replace older Square D Q2 series breakers?
Yes, the PowerPacT Q-frame is a direct drop-in replacement for discontinued Q2 series circuit breakers, such as the Q22200, in I-Line panelboards.
What does the "J" in the QJA frame designation represent?
The "J" indicates the interrupting rating tier for the PowerPacT Q-frame series. A J-tier breaker provides a 100kAIC rating at 240VAC.
What is the recommended lug torque for the load side terminals on this 200A breaker?
The load side lugs for the 4 AWG to 300 kcmil conductors should be torqued to 250 lb-in (28 N-m).
How does the I-Line connection work on the QJA222001?
The breaker features a plug-on jaw configuration on the line side that snaps directly onto the I-Line bus, while the load side utilizes standard mechanical box lugs for cable connections.
How can I visually verify if the QJA222001 has tripped?
When a fault occurs, the toggle handle snaps to a center tripped position between ON and OFF, providing clear visual indication that the breaker has operated.
Does this breaker include a push-to-trip feature for safety testing?
Yes, PowerPacT Q-frame circuit breakers feature an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
