Description
Built for commercial and industrial power distribution, the Square D KCL34225 delivers reliable overcurrent protection in a 225A package. This legacy K-Frame MCCB features an extra-high interrupting capacity of 65kA at 480VAC. Equipped with a thermal-magnetic trip unit, it provides fixed thermal and adjustable magnetic (LI) functions. The breaker mounts into Square D switchboards using feed-thru lugs. For future upgrades, this unit is replaced by the modern PowerPacT J-Frame series (JJL36225).Specifications

Product FAQs
7 answersWhat is the modern replacement for the legacy Square D KCL34225 circuit breaker?
The KCL34225 is a legacy K-Frame breaker. For modern upgrades or replacements, Square D recommends the PowerPacT J-Frame series, specifically the JJL36225, which provides equivalent 225A protection and a 65kAIC rating at 480VAC.
What types of equipment are compatible with the KCL34225 breaker?
This unit mount K-Frame breaker is designed for use in compatible Square D enclosures, switchboards, and panelboards that accept feed-thru lug connections.
What wire sizes and materials are accepted by the lugs on the KCL34225?
The standard lugs on this breaker accept wire gauges from 4 AWG up to 350 kcmil. They are rated for use with both aluminum and copper conductors.
What does the LI trip function code mean on the KCL34225?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time and Instantaneous protection. The thermal element is fixed, while the magnetic instantaneous trip is adjustable to coordinate with specific load requirements.
Can the KCL34225 be used on 240V systems?
Yes. While it is rated for 65kAIC at 480VAC, it is also fully rated for 240VAC applications, where it provides an increased interrupting capacity of 100kAIC.
Does the KCL34225 require a specific mounting configuration?
Yes, this is a unit mount circuit breaker with a feed-thru connection type. It is designed to be bolted directly to the mounting pan or backplate rather than plugging onto a busbar.
How do I verify the KCL34225 has tripped?
The operating handle will move to a center position between ON and OFF when a fault condition causes it to trip. You must move the handle fully to the OFF position before turning it back ON to reset the breaker.
