B-LINE JHMFS10X – Frequently Asked Questions
1) Which Eaton breaker frame sizes does the JHMFS10X handle mechanism fit?
The JHMFS10X is built for Eaton J and K frame molded case circuit breakers. If your breaker is a smaller or larger frame class, this mechanism is the wrong part, so confirm the frame designation stamped on the breaker before ordering.
2) Can the JHMFS10X flange-mounted handle be used on an outdoor breaker enclosure?
Yes. The JHMFS10X handle mechanism is rated NEMA 3R/4X, which covers rain and falling-water outdoor exposure plus corrosion-resistant washdown duty, so it suits outdoor and wet or corrosive indoor locations such as water treatment and food processing areas.
3) How far can the breaker be from the operating handle with the JHMFS10X?
The mechanism ships with a 10 ft shaft, so the handle can be mounted up to that distance from the J or K frame breaker it operates. That is what lets you put the operator on an enclosure door or a remote panel face while the breaker sits deeper in the assembly. Longer runs need a different shaft-length part number.
4) What is the exact manufacturer part number and UPC for this Eaton handle mechanism?
The manufacturer part number is JHMFS10X, UPC 782113527772, branded B-Line. There is a single configuration, so there are no finish or length options to specify when ordering.
5) What are the shipping dimensions and weight of the B-Line JHMFS10X handle mechanism?
Spec data lists the JHMFS10X at 20 in length/depth, 8 in width, 2.5 in height, and 19 lb. The 20 in figure reflects the packaged 10 ft shaft assembly, so plan for a long carton rather than a small parts box when receiving it on a job site.
6) Which Eaton enclosure line is the JHMFS10X handle mechanism part of?
The JHMFS10X belongs to the Series G family, Eaton's enclosure and breaker accessory line, so it matches other Series G components if you are standardizing operators across multiple gear locations in a facility.
