Product FAQs
8 answersWhat equipment is compatible with the KDL32225 circuit breaker?
This unit-mount breaker is designed for installation in Square D enclosures, switchboards, and compatible 3-phase QO load centers that accept K-frame main breakers.
How does the feed-thru connection type affect installation?
As a feed-thru, unit-mount breaker, it bolts directly to the backpan of an enclosure or switchboard and uses wire lugs on both the line and load sides, rather than plugging into a busbar.
What wire sizes and materials are supported by the KDL32225 lugs?
The factory-installed lugs are dual-rated for both aluminum and copper conductors, accepting wire sizes from 6 AWG up to 350 kcmil.
How does the thermal-magnetic trip unit function on this breaker?
The fixed thermal-magnetic trip unit provides Long-Time (L) protection for gradual overloads and Instantaneous (I) protection for immediate short circuits. Both the thermal and magnetic trip points are fixed and non-adjustable.
What does the 25kAIC rating signify for this K-frame breaker?
The 25kAIC (Amps Interrupting Capacity) rating means the breaker can safely interrupt up to 25,000 amps of fault current at 240V AC, protecting downstream equipment from severe short circuits.
Can the KDL32225 be used to replace a QDL32225?
Yes, it serves as a functional substitute for QDL32225 configurations in many applications, providing the same 225A capacity and 25kAIC rating at 240V AC.
Can this breaker be installed in a 480V or 600V system?
No, the KDL32225 is strictly rated for a maximum of 240V AC. Installing it in higher voltage systems violates its UL listing and safety ratings.
Does the KDL32225 include ground-fault or arc-fault protection?
No, this is a standard thermal-magnetic breaker designed solely for overcurrent and short-circuit protection. It does not contain GFCI or AFCI circuitry.
