The Shaft Handle M
echanism 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, plus NEMA 4 and 4x applications, depending on
the accessory components selected. An operating handle, flexible shaft, and mechanism are required for standard applcation. Three lengths of shafts are available for
use with the range of depths of various enclosures (4’, 5’,
and 6’). When selecting the length of the Flexible Shaft,
ensure Minimum Bending Radius of 5 inches is maintained to operate properly.
