B-LINE WHM5R24 – Frequently Asked Questions
1) What breakers does the B-Line WHM5R24 handle mechanism work with?
The WHM5R24 is built for Eaton Series C molded case circuit breakers in the N-frame size. If the breaker in your enclosure is a different Eaton frame, this mechanism is not the one to order, since the operating mechanism has to match the frame it clamps to.
2) How long is the shaft on the WHM5R24 breaker handle mechanism?
The shaft measures 24 inches. That length determines how far the door handle can sit from the breaker itself, so measure from the breaker's operating shaft position to where the handle will mount on the door before committing. A 24 inch shaft covers a tall enclosure where the breaker is mounted well below the handle location; shafts are commonly cut to fit shorter runs.
3) Do I still need the breaker itself if I order the WHM5R24?
Yes. The WHM5R24 is the handle mechanism only, the door handle, shaft and operating linkage that let you throw an Eaton Series C N-frame breaker from outside the enclosure. The circuit breaker and the enclosure are separate purchases.
4) Is the WHM5R24 a rotary handle or a flange-mounted lever?
Rotary. You turn the handle on the face of the enclosure door, and the shaft transmits that motion through the door to the breaker inside. That means the breaker can be operated with the door closed, which is how electricians and plant maintenance normally want a molded case breaker in an enclosure set up.
5) What part number do I give my supplier for the Eaton Series C N-frame 24 inch rotary handle mechanism?
Order it as WHM5R24, a B-Line part for Eaton Series C N-frame molded case breakers with a 24 inch shaft. The manufacturer publishes a spec sheet under that same number if your drawing needs a cut sheet attached.
