Product FAQs
6 answersWhat circuit breaker frames are compatible with the HKB3225T trip unit?
The HKB3225T is an interchangeable trip unit designed to fit Westinghouse, Eaton, and Cutler-Hammer KB and HKB (Mark 75) molded case circuit breaker frames.
Is the HKB3225T a complete circuit breaker?
No, this catalog number represents the thermal-magnetic trip unit only. It must be installed into a compatible 3-pole KB or HKB frame to operate as a complete molded case circuit breaker.
What trip functions are included on the HKB3225T?
This thermal-magnetic trip unit features Long-Time and Instantaneous (LI) protection to guard against overloads and short circuits in commercial and industrial applications.
Can I use this Westinghouse trip unit in an Eaton or Cutler-Hammer panel?
Yes. Eaton acquired the Westinghouse distribution equipment business, so the HKB3225T is physically and electrically interchangeable with Eaton and Cutler-Hammer branded KB and HKB frames.
Can the HKB3225T trip unit be replaced in the field?
Yes, because it is an interchangeable trip unit, a qualified electrician can install or replace the HKB3225T in the field without needing to replace the entire breaker frame.
What safety precautions should be taken when installing the HKB3225T?
Installation should only be performed by a licensed electrician. Ensure all power to the panelboard or switchboard is completely de-energized and verified with a voltage meter before installing the trip unit into the breaker frame.
