Description
Built for heavy-duty power distribution, this 200-ampere molded case circuit breaker features a classic K-Frame design with an interchangeable trip unit. It handles demanding electrical loads across 600VAC commercial systems. The bolt-on configuration installs securely into Cutler-Hammer CDP panelboards, Pow-R-Line C load centers, and legacy switchboards. Facility managers often substitute this model with the KD3200, provided a TAD3 adapter is utilized. It delivers reliable LI trip functions.Specifications

Product FAQs
6 answersWhat equipment is the KA3200 circuit breaker compatible with?
This legacy K-frame breaker mounts into Westinghouse and Cutler-Hammer Pow-R-Line C panelboards, CDP enclosures, switchboards, and motor control centers.
What is the modern replacement for the legacy KA3200 circuit breaker?
The Eaton Series C KD3200 is the direct modern replacement for the legacy KA3200. Depending on your specific panelboard or enclosure, installing the newer KD-frame breaker may require an adapter or spacer.
Can the KA3200 circuit breaker be reverse fed?
No. According to Eaton specifications, legacy KA-frame circuit breakers are not suitable for reverse feed applications.
What wire sizes are accepted by the standard lugs on the KA3200?
The standard lugs accept 4 AWG to 350 kcmil aluminum or copper wire. Always apply the manufacturer recommended torque to the lugs during installation to ensure a secure connection and prevent overheating.
How does the adjustable magnetic trip work on the KA3200?
The KA3200 features a thermal-magnetic trip unit with a fixed thermal element for standard overload protection and an adjustable magnetic element. This allows panel builders and electricians to fine-tune the instantaneous short-circuit response to match specific load requirements.
Is the KA3200 rated for DC voltage applications?
Yes, in addition to its AC ratings, the KA3200 is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 10kAIC.

I have purchased multiple breakers (of fairly large size) from SuperBreakers and their pricing has been excellent and the delivery time spot on. I would highly recommend them

I have ordered many breakers through SuperBreakers with no issues until this order. I ordered this breaker and it wasn't shipped. I sent a message and was told that a mistake was make in shipping and that they would next day air the breaker to me. 5 days later (weekend in there) the breaker arrived. Not next day air, but shit happens. Sent the breaker still in the box out with my electrician and received a call from him that the breaker that was sent was a KAL36100 not the KA36100. I reached out to SuperBreakers and was told the correct breaker would be next day aired that day and I was emailed a shipping label to send back the incorrect one. This time it arrived the next day and was installed. This error cost my customer a couple days with out power to a dimmer cabinet and about 2 extra hours of labor, but all was okay in the end. Mistakes happen. The help and quick responses to my emails I received from Mike David showed me enough about this company. I look forward to my next order. Thank you for working this situation out in timely manor.
