Eaton F1S03C – Frequently Asked Questions

1) Will the Eaton F1S03C flex shaft handle mechanism work on my F-Frame breaker?
The F1S03C is built for Eaton Series C F-Frame molded case breakers in the Frame J-K size. If your breaker is an F-Frame Series C with a J or K frame designation, this is the matching handle mechanism. Other Eaton frame sizes (and non-Series C breakers) use a different mechanism, so confirm the frame letter stamped on the breaker before ordering.
2) How far can the handle be mounted from the breaker with the F1S03C?
The flexible shaft is 3 ft long, so the operating handle can sit up to that distance from the breaker itself. That is what lets you route the shaft around obstructions inside an enclosure and land the handle on the door or a side panel rather than directly over the breaker. If your handle location is more than 3 ft from the breaker, you need a longer shaft version.
3) Can I switch the breaker without opening the enclosure door using this Eaton accessory?
That is the point of it. The F1S03C puts an external operating handle on the enclosure so an electrician or maintenance tech can turn the F-Frame breaker on and off with the door closed, which keeps the operator out of the arc flash boundary of an opened panel.
4) Do I need a flex shaft mechanism or a direct variable-depth handle for my panelboard?
A flex shaft mechanism like the F1S03C is the choice when the handle cannot sit directly in line with the breaker, because the 3 ft flexible shaft bends around barriers, gutters, and other gear inside the enclosure. A rigid direct-drive handle only works when the door handle lines up with the breaker operator. Pick the flex shaft for off-center handle locations or deep enclosures.
5) How much room do I need inside the enclosure for the Eaton F1S03C handle mechanism?
Plan for a footprint of 18.8 x 20.1 x 2.6 inches for the mechanism assembly, plus routing room for the 3 ft shaft. The 2.6 inch dimension is the shallow one, which is what matters most for clearance between the breaker and the enclosure door.
6) Is the F1S03C a complete handle kit or do I need the breaker separately?
It is an accessory only. The F1S03C supplies the flex shaft handle mechanism for remote operation; the Eaton Series C F-Frame breaker, the enclosure, and any door cutout work are separate. Order it against a breaker you already have or are specifying in the same J-K frame size.
7) What part number do I order for the Eaton 3 ft flex shaft handle for F-Frame breakers?
The Eaton manufacturer part number is F1S03C, a single configuration covering the Series C F-Frame J-K application with the 3 ft shaft. There are no finish or size options to specify on it.
