Product FAQs
6 answersWhat panelboards are compatible with the KCP34225?
This legacy K-Frame breaker is designed for use with Square D I-Line panelboards. It utilizes a bolt-on connection rather than a plug-on design.
What are the wire size requirements for the KCP34225 lugs?
The standard lugs on this breaker accept either aluminum or copper (Al/Cu) conductors, accommodating wire gauges from 4 AWG up to 350 kcmil.
What do the LI trip function and adjustable magnetic settings mean on the KCP34225?
The LI designation means this thermal-magnetic breaker provides Long-Time (L) and Instantaneous (I) protection. It features a fixed thermal element for standard overload protection and an adjustable magnetic element, allowing installers to fine-tune the short-circuit trip threshold.
Is the KCP34225 suitable for high-fault commercial applications?
Yes, it is built for heavy-duty power distribution with an extra-high interrupting capacity. It can safely interrupt up to 65kA at 480VAC and 100kA at 240VAC.
What frame size does the KCP34225 belong to?
It is part of the legacy Square D K-Frame family, specifically designated as a KCL frame molded case circuit breaker.
Can this 3-pole breaker be applied on 277V systems?
Yes, while it has a maximum voltage rating of 480VAC, it is fully compatible with 240V, 277V, and 480V AC electrical systems.
