B-LINE JHMFS05X – Frequently Asked Questions
1) Which Eaton circuit breaker frames does the JHMFS05X handle mechanism fit?
The JHMFS05X is built for Eaton J-K frame molded case circuit breakers. If your breaker is a different frame size, this flange-mounted handle mechanism is the wrong part, since the operating mechanism is matched to the breaker frame it clamps onto.
2) Can the JHMFS05X handle mechanism be used on an outdoor or washdown enclosure?
Yes. The JHMFS05X carries a NEMA 3R/4X rating, so it suits outdoor rain-exposed enclosures and corrosion-resistant or washdown environments. That rating is for the handle mechanism itself; the enclosure it mounts to has to be rated for the same duty.
3) How long is the shaft on the JHMFS05X, and will it reach a breaker mounted deep in a tall enclosure?
The JHMFS05X ships with a 5 foot shaft, so it will span a tall floor-mounted or deep enclosure where the breaker sits well below the door-mounted handle. The shaft is cut to the height you actually need during install.
4) What exactly does a circuit breaker handle mechanism do, and do I still need the breaker?
A handle mechanism is the external operator only. It gives you a door-mounted handle and a shaft that turns the breaker on and off without opening the enclosure, and it is where you apply your lockout. The breaker itself is a separate purchase. The JHMFS05X is the J-K frame version in Eaton's Series G line.
5) What is the manufacturer part number to specify for the Eaton J-K frame 5 foot handle mechanism?
Order it as JHMFS05X. That single catalog number covers the Series G flange handle mechanism for J and K frame molded case breakers with the 5 foot shaft, rated NEMA 3R/4X.
6) What are the shipping dimensions and weight of the JHMFS05X handle mechanism?
Spec data lists the JHMFS05X at 20 inches by 8 inches by 2.5 inches and 19 pounds. The long dimension reflects the 5 foot shaft being shipped in sections with the handle and breaker-side mechanism.
