DESCRIPTION OF OPERATION SE- lOOM
The SE- lOOM switch has a direct mechanical drive and the closing and
opening energy is supplied by the operator.
When operating the switch, the handle should be rotated with a posi­
tive motion throughout its entire stroke.
Closing the switch is accomplished by inserting the operating handle
{l) Fig. 3 into the handle socket provided in the operating hub {7)
Fig. 1 in the enclosure and rotating in a counterclockwise direction
as far as possible {approximately 180°) .
During the closing cycle the auxiliary blade (7) Fig.
out of the arc chute until the primary blades (ll) are almost closed.
Just before the primary contacts (5) Fig. 7 touch, the auxiliary blade
is released and will be the first part to close.
The mechanism has a direct gear drive to the main shaft of the switch
and depends entirely on the operator to produce a smooth and positive
motion to satisfactorily close.
To open the switch insert the operating handle into the handle socket
and rotate in a clockwise direction as far as possible {approximately
180 degrees) .
The primary contacts (5
