Eaton SM100SFR – Frequently Asked Questions

1) Will the Eaton SM100SFR handle mechanism fit my molded case circuit breaker?
The SM100SFR handle mechanism is built for Eaton Frame J-K molded case circuit breakers rated 30, 60 or 100A. If your breaker is a different frame designation or sits outside that amp range, this is not the right mechanism. Confirm the frame letter stamped on the breaker before ordering.
2) Is the Eaton SM100SFR a right-mount or left-mount handle mechanism?
Right mount. The SM100SFR is configured for right-side mounting on the breaker, which fixes the handle orientation and the direction of operation. A left-mount application needs a different part number, so check which side of the enclosure the handle has to come off before you order.
3) Can I use this Eaton part to restore the external handle on an older breaker instead of replacing the whole breaker?
That is exactly what it is for. The SM100SFR is an Eaton renewal part that restores external operating handle function on an in-service Frame J-K breaker, so a worn or damaged handle mechanism can be swapped rather than pulling and replacing the breaker and its terminations. It comes out of Eaton's aftermarket renewal parts and life extension program.
4) How much room do I need in the enclosure for this Eaton handle mechanism?
Allow for a 6.6 in width, 11.4 in length/depth and 4.8 in height. That depth is the number that usually causes trouble in a shallow panel or an existing retrofit enclosure, so measure the free space behind the door before committing.
5) Does the Eaton SM100SFR include the circuit breaker itself?
No. This is the handle mechanism accessory only, an external operating handle assembly for a Frame J-K breaker. The breaker, the enclosure and any mounting hardware specific to your panel are separate.
6) Where is an Eaton Frame J-K handle mechanism typically used?
Mostly in panelboard and switchgear servicing on commercial and industrial distribution gear, where a facility electrician needs the door-mounted handle working again on an existing molded case breaker. It shows up on maintenance and repair work orders and on life extension programs where the existing equipment is staying put.
