B-LINE JHMFS08X – Frequently Asked Questions
1) What is the B-Line JHMFS08X used for on a circuit breaker enclosure?
The JHMFS08X is a flange-mounted handle mechanism for an Eaton molded case circuit breaker. It puts the breaker's operating handle on the outside of the enclosure door, so the breaker can be switched on and off, and the door interlocked, without opening the enclosure. It is part of Eaton's Series G line.
2) Can the JHMFS08X handle mechanism be used on an outdoor or washdown enclosure?
Yes. The JHMFS08X handle mechanism carries a NEMA 3R/4X rating, so it suits rain-tight outdoor enclosures and corrosion-resistant/washdown installations. Match it to an enclosure with an equal or lower rating requirement, and keep the door gasket intact when you cut the flange opening.
3) How long is the operating shaft on the JHMFS08X, and how deep an enclosure will it reach?
The shaft supplied with the JHMFS08X is 8 feet long. That is a cut-to-length shaft, so it covers tall enclosures and deep-set breaker positions, and you trim it to the actual distance between the breaker and the door flange during install.
4) Does the JHMFS08X include the circuit breaker?
No. The JHMFS08X is an accessory handle mechanism only. You order the molded case breaker and the enclosure separately; this part provides the external handle, shaft and flange hardware that ties the two together.
5) What part number do I quote for the Eaton Series G flange handle mechanism?
Order it as JHMFS08X, the manufacturer part number for the Eaton Series G molded case breaker handle mechanism with the 8 foot shaft. There is a single configuration, so there is no finish, handing or shaft-length option to specify on the purchase order.
6) What are the shipping dimensions and weight of the B-Line JHMFS08X handle mechanism?
The JHMFS08X is listed at 20 inches length/depth, 8 inches wide and 2.5 inches high, weighing 19 lb. The 20 inch figure is driven by the long operating shaft, so plan for a long carton rather than a small parts box when you stage it on site.
