Product FAQs
6 answersWhat type of panelboards accept the KC34200?
This circuit breaker features an I-Line plug-on connection and is exclusively compatible with Square D I-Line panelboards and switchboards. It will not fit in standard load centers or bolt-on panel configurations.
What wire gauges are supported by the standard KC34200 lugs?
The standard mechanical lugs on this breaker accommodate wire sizes ranging from 4 AWG up to 350 kcmil.
Is the trip unit on the KC34200 adjustable?
Yes, while the thermal element for long-time overload protection is fixed at 200A, the magnetic (instantaneous) trip function features an adjustable dial to help coordinate with downstream devices and specific inrush current requirements.
Is the legacy K-Frame KC34200 still manufactured?
No, the original Square D K-Frame series is officially obsolete. Supplying these legacy frames allows facilities to replace failed breakers without undergoing costly panel retrofits.
What is the current PowerPact replacement for the KC34200?
For facilities upgrading their distribution equipment, the legacy KC34200 crosses over to the modern Square D PowerPact J-Frame series, specifically catalog number JJA36200. This modern equivalent matches the 200A rating, 3-pole I-Line configuration, and 65kAIC at 480VAC interrupting capacity.
Does the KC34200 support DC voltage applications?
Yes. Alongside its standard alternating current ratings, this breaker is certified for direct current systems up to 250VDC, where it provides a 10kA interrupting rating.
