Product FAQs
6 answersWhat enclosures are compatible with the HK3225F circuit breaker?
This K-frame device is designed for panel mount installations in Eaton Series C panelboards, standard switchboards, and motor control centers.
Will the Eaton HK3225F replace an older Westinghouse HK3225F?
Yes. Eaton acquired the Westinghouse distribution equipment division, and this Series C K-frame breaker serves as a direct replacement for legacy Westinghouse models with the same catalog number.
What does the H in the HK3225F catalog number signify?
The H indicates that this is a High Interrupting Capacity model within the Series C K-frame family, offering elevated fault protection compared to standard KD breakers.
Can the HK3225F thermal-magnetic breaker be reverse fed?
Yes. Eaton Series C K-frame thermal-magnetic circuit breakers are suitable for reverse feed applications, allowing power to be supplied to either the line or load terminals.
What is the difference between the HK3225F and the HKD3225?
The HK3225F designates the breaker frame configuration, whereas the HKD3225 refers to the complete, factory-assembled breaker. Both utilize the same Series C K-frame footprint and provide identical thermal-magnetic protection.
How can I manually verify the mechanical trip function on this breaker?
You can periodically exercise the operating mechanism by pressing the PUSH-TO-TRIP button with a small screwdriver. This safely tests the mechanical tripping function without requiring an electrical fault.
