Product FAQs
6 answersHow does the KDL32150 mount into compatible equipment?
This is a unit-mount circuit breaker with a feed-thru connection. It secures directly to Square D QO 3-phase load centers, enclosures, and switchboards using line and load lugs, rather than plugging onto a bus bar.
Does the KDL32150 have adjustable trip settings?
No, this breaker utilizes a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous (LI) protection.
Is the Square D KDL32150 still in active production?
No, the KDL frame is a legacy molded case circuit breaker that is no longer manufactured by Schneider Electric. It is typically sourced as an exact replacement part to maintain existing electrical systems.
Can I use a KGL breaker to replace a KDL breaker?
Yes, the KGL series is the higher-interrupting counterpart to the KDL series. A KGL32150 has the same physical dimensions and mounting but offers a higher interrupting rating of 65kAIC at 240V, compared to the 25kAIC rating of the KDL32150.
What is the difference between the KDL32150 and QDL32150?
While both are 150A, 3-pole, 240V breakers with a 25kAIC rating, they belong to different frame families (K-frame vs. Q-frame) and have different physical dimensions. The KDL32150 is often used as a heavy-duty upgrade to the standard QDL32150 in compatible switchboards and enclosures.
Is the KDL32150 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
