Product FAQs
4 answersWhat type of panels or enclosures accept the KDL32175 breaker?
This K-Frame breaker is designed for use in Square D QO 3-phase load centers, commercial switchboards, and dedicated Square D enclosures. As a unit mount, feed-thru breaker, it requires a bolted backpan installation rather than snapping onto a standard busbar.
What are the conductor requirements for wiring the KDL32175?
The breaker is equipped with standard lugs that accept either aluminum or copper (Al/Cu) wire. You can use conductor sizes ranging from 6 AWG up to 350 kcmil to support its 175A rating.
Are the thermal and magnetic trip points adjustable on this model?
No. The KDL32175 features a fixed thermal magnetic trip unit. While it provides both Long-Time (L) and Instantaneous (I) protection functions, neither the overload threshold nor the short-circuit pickup can be modified by the user.
Is the KDL32175 a current production model or a legacy frame?
The KDL series belongs to the legacy K-Frame family of molded case circuit breakers by Square D. It is typically sourced to replace existing 175A feed-thru breakers in older electrical systems without requiring a panel retrofit.
