Eaton JGHMVD12B – Frequently Asked Questions

1) Which Eaton breaker frames does the Series G S2 rotary handle mechanism fit?
The Series G S2 handle mechanism is built for JG-frame Eaton molded case circuit breakers only. If the breaker in your panel is a different Series G frame size, this mechanism will not mount to it; match the accessory to the frame letter stamped on the breaker before ordering.
2) What is the difference between the Eaton JGHMVD12B and JGHMVD24B handle mechanisms?
Both are Series G S2 rotary handle mechanisms for JG-frame breakers, ordered as two separate models: JGHMVD12B and JGHMVD24B. Both carry the same black/blue handle and the same 5 in mechanism height, so the choice is about matching the exact Eaton part number called out on your panel drawing or the one already installed on the enclosure.
3) Can I operate a Series G JG-frame breaker from outside the enclosure without opening the door?
That is exactly what this accessory is for. The S2 rotary handle mechanism mounts to a JG-frame Series G breaker and brings operation to the outside of the panel or enclosure door, so an electrician or maintenance tech can switch the breaker on and off with the door closed.
4) Is this Eaton handle a complete breaker, or just an accessory?
Accessory only. The S2 rotary handle mechanism is an operating handle for a molded case circuit breaker, not the breaker itself. You still need the JG-frame Series G breaker, and the enclosure or panelboard it mounts in, to make a working assembly.
5) How much clearance do I need in the enclosure for the Eaton JG handle mechanism?
Plan for a mechanism height of 5 in when you lay out the breaker inside the can. That is the published height of the S2 handle mechanism itself, and it has to clear the door and any adjacent gear once it is coupled to the JG-frame breaker.
6) Can I add this rotary handle to an existing Series G JG-frame breaker already in service?
Yes, retrofitting an installed JG-frame Series G breaker is one of the listed uses for this mechanism, along with new panelboard and switchgear builds and control panel applications. The breaker has to be a JG frame in the Series G line for the mechanism to couple to it.
7) Does the Eaton S2 handle show whether the breaker is on or off?
Yes. The handle is a black/blue color scheme used for visual on/off status indication, so a tech walking the room can see breaker position at a glance without opening the door.
