Product FAQs
6 answersWhat is the difference between the Eaton KD3225 and KDC3225 circuit breakers?
The primary difference is the interrupting capacity. The KD3225 is a standard-rated breaker at 35 kAIC at 480VAC, while the KDC3225 is an ultra-high interrupting capacity breaker rated at 100 kAIC at 480VAC. Both share the same physical K-frame dimensions and 225A rating.
What enclosures and equipment are compatible with the KDC3225 breaker?
This K-frame breaker is designed for installation in Eaton Series C panelboards, switchboards, and motor control centers.
Can I use the Eaton KDC3225 to replace an older Westinghouse K-frame breaker?
Yes, Eaton Series C breakers are direct replacements for legacy Westinghouse and Cutler-Hammer Series C breakers with matching frame sizes and specifications.
What does the LI trip function on the KDC3225 indicate?
The LI designation means the breaker is equipped with Long-Time and Instantaneous trip functions. The KDC3225 features a fixed thermal element for Long-Time overload protection and an adjustable magnetic element for Instantaneous short-circuit protection.
What type of conductors can be used with the standard lugs on the KDC3225?
The standard lugs are dual-rated for both aluminum and copper (Al/Cu) conductors, accepting wire sizes from 3 AWG up to 350 kcmil.
Can the KDC3225 be applied in direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for 250VDC systems, providing a 22 kAIC interrupting rating for DC applications.
