Product FAQs
7 answersDoes the HKB3250F include a trip unit?
No, the HKB3250F is a frame-only component. It requires a separately sourced, compatible interchangeable trip unit to provide thermal-magnetic protection.
What determines the continuous current rating of the HKB3250F frame?
While the HKB3250F frame has a maximum capacity of 250 amps, the actual continuous current rating is established by the specific interchangeable trip unit installed.
Is the Westinghouse HKB3250F interchangeable with Eaton or Cutler-Hammer breakers?
Yes. Eaton acquired the Westinghouse distribution and control business, so the HKB3250F frame is physically and electrically interchangeable with equivalent Cutler-Hammer and Eaton HKB frame circuit breakers.
Are line and load lugs included with the HKB3250F frame?
As a frame-only unit, the HKB3250F does not include line and load lugs. Lugs must be specified and installed separately based on your required wire size and conductor material.
What type of equipment accepts the HKB3250F circuit breaker frame?
The HKB3250F is a legacy K-frame molded case circuit breaker designed for bolt-on installation in compatible Westinghouse, Cutler-Hammer, and Eaton panelboards, switchboards, and motor control centers.
What does the F suffix indicate in the HKB3250F catalog number?
In Westinghouse and Eaton nomenclature, the F suffix designates that the component is a frame only, meaning it is supplied without a trip unit or lugs.
Can I swap trip units while the HKB3250F frame is energized?
No. For safety and to prevent arc flash hazards, the circuit breaker must be completely de-energized and isolated from all power sources before installing or swapping a trip unit.
