Product FAQs
9 answersWhat type of panelboard is the QJA222252 designed to fit?
This breaker features an I-Line style plug-in connection and is exclusively compatible with Square D I-Line panelboards and switchboards. It will not fit NQ or NF series panels.
What does the J in the QJA222252 catalog number indicate?
In the Square D PowerPacT Q-Frame series, the J designates the interrupting rating. The QJA series provides a 100kAIC rating at 240VAC, which is the highest interrupting capacity in the Q-Frame family.
How does the QJA222252 differ from QBA, QDA, and QGA breakers?
The difference lies in the interrupting capacity at 240VAC. The QBA is rated for 10kAIC, the QDA for 25kAIC, the QGA for 65kAIC, and the QJA222252 offers the maximum 100kAIC rating. They share the same physical dimensions and I-Line mounting.
What is the recommended tightening torque for the load side lugs on this breaker?
The load side lugs, which accept 4 AWG to 300 kcmil aluminum or copper wire, should be torqued to 248 lb-in or 28 N.m to ensure a secure and compliant electrical connection.
Can the QJA222252 be used in a 480V or 600V electrical system?
No, this Q-Frame breaker is strictly rated for a maximum of 240VAC. It is not suitable for 480V or 600V distribution systems.
How is the QJA222252 physically installed into the panel?
It utilizes an I-Line plug-on design for the line side, which snaps directly onto the panelboard bus assembly. The load side features mechanical lugs for traditional wire termination.
Does this breaker include a push-to-trip feature for testing?
Yes, Square D PowerPacT Q-Frame breakers include an integral push-to-trip button on the front cover, allowing you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
What type of trip unit is equipped in the QJA222252?
It features a fixed thermal-magnetic trip unit. The thermal element provides long-time overload protection, while the magnetic element provides instantaneous short-circuit protection. Neither function is field-adjustable on this specific model.
What safety precautions should be taken before installing this I-Line breaker?
Always de-energize the panelboard or switchboard before installation. Verify the power is off using a properly rated voltage sensing device, and wear appropriate Personal Protective Equipment in accordance with NFPA 70E guidelines.
