Product FAQs
6 answersWhat type of equipment is the KHL26225 breaker designed to be installed in?
It is compatible with Square D enclosures, switchboards, and motor control centers that accept unit-mounted K-Frame breakers.
What wire sizes and materials do the feed-thru lugs on the KHL26225 accept?
The factory lugs accommodate conductor sizes from 4 AWG up to 350 kcmil and are rated for both aluminum and copper wire.
Does this breaker plug onto a panelboard bus?
No, the KHL26225 is a unit-mount breaker. It must be bolted directly to the mounting surface or backpan and wired via the feed-thru lugs.
How does the thermal magnetic trip unit operate on this K-Frame breaker?
The LI (Long-Time and Instantaneous) trip unit features a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection.
Can the KHL26225 be used in direct current systems?
Yes, in addition to its AC ratings, this breaker is rated for 250VDC applications with a 10kA interrupting capacity.
Is the KHL26225 still in active production by Square D?
The KHL series is classified as a legacy K-Frame molded case circuit breaker. Modern replacements typically fall under the PowerPact series, though this exact frame is often required for direct replacements in existing switchboards.
