Product FAQs
8 answersWhat equipment is compatible with the KDB3200?
This K-frame breaker is designed for installation in Eaton Series C panelboards, motor control centers, and switchboards.
Can I use the KDB3200 to replace a legacy Cutler-Hammer KA3200?
Yes, K-frame Series C breakers share the same physical dimensions, mounting footprint, and terminal centerlines as legacy KA, HKA, and DA breakers. Note that the handle throw and specific terminal connections may differ slightly from the older models.
What is the difference between the Eaton KD3200 and KDB3200?
The KD3200 features an interchangeable trip unit, while the KDB3200 is a factory-assembled complete breaker with a non-interchangeable thermal-magnetic trip unit. Both share the same K-frame footprint and interrupting capacity.
Can the Eaton KDB3200 be reverse fed?
Yes, Eaton K-frame circuit breakers with non-interchangeable trip units, such as the KDB3200, are suitable for reverse feed applications.
Which replacement lug kit is required for the KDB3200?
To support the maximum 350 kcmil wire size listed for this breaker, use the Eaton TA350K terminal kit. These standard K-frame lugs accept both aluminum and copper conductors.
Does the KDB3200 provide ground fault protection?
No, this breaker features an LI (Long-Time and Instantaneous) thermal-magnetic trip unit. It provides standard overload and short-circuit protection but does not include ground fault monitoring.
Is the KDB3200 rated for 100 percent continuous operation?
No, standard thermal-magnetic K-frame breakers like the KDB3200 are rated for 80 percent continuous operation. Eaton requires specific electronic trip models, such as the CKD or CHKD, for 100 percent rated applications.
Can I adjust the trip settings on the KDB3200?
No, this specific model features a fixed thermal and fixed magnetic trip unit. It does not offer adjustable dials for long-time or instantaneous pickup.
