Product FAQs
8 answersWhich panelboards are compatible with the QDA221753 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on I-Line bracket and will not fit in standard NQ, NF, or QO series panels.
What does the '3' at the end of the QDA221753 catalog number indicate?
In Square D PowerPacT Q-frame I-Line breakers, the final digit specifies the phase connection on the panelboard bus. The '3' designates a BA phase connection.
How much mounting space does this 2-pole breaker require in an I-Line panelboard?
This 2-pole Q-frame I-Line circuit breaker requires 3 inches of mounting height space on the panelboard bus.
What is the recommended lug torque for the load terminals on the QDA221753?
The load-side mechanical lugs accept 4 AWG to 300 kcmil aluminum or copper wire and should be torqued to 248 lb-in (28 N.m).
Are the thermal and magnetic trip settings adjustable on the QDA221753?
No. This breaker features a fixed thermal and fixed magnetic trip unit. The magnetic hold current is factory set at 1200A, and the magnetic tripping current is 2400A.
Can the QDA221753 be used in DC electrical systems?
No. Square D PowerPacT Q-frame circuit breakers are designed for AC systems only and do not carry a DC voltage rating.
Does this breaker include a push-to-trip feature?
Yes. It includes 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 legacy breaker does the QDA221753 replace?
The QDA221753 is the direct modern replacement for the obsolete Square D Q22175BA. It provides the same 175-amp rating, 2-pole BA phase connection, and I-Line mounting, but utilizes the updated PowerPacT Q-frame design.
