GENERAL INFORMATION

The Flex Shaft handle mechanism provides a means of

externally operating the circuit breaker and can be

applied to enclosures of varying heights and depths. The

handle can be used with NEMA 1, 3R, and 12 enclosure

applications, depending on the accessory components

selected. An operating handle, flexible shaft, and mecha-

nism are required for standard application. Nine lengths of

shafts are available for use with the wide range of depths of

various enclosures (2' through 10'). When

selecting the length of the Flexible Shaft, ensure Mini-

mum Bending Radius of 4 inches is maintained to

operate properly. The standard method of shipment

includes the mechanism preset at the factory. If minor

field adjustments are required, see Fig. 1-3. For this

publication, the term circuit breaker shall also include the

molded case switch and motor circuit protector (HMCP).
