IT is a three position Switch. The swith atre of two types -
Having lockable Trip position and other with spring return
to normal Neutral position.
For manual operation this switch is used to TRIP a breaker
by moving it towards trip position and close by moving it
towards Close position.
In neutral position all the operations on AUTO mode or from
remote can be done, as per the scheme.
For keeping the breaker in OFF condition or for isolation,
the switch can be kept in lockable TRIP position, if that
facility is available in the switch.Read from previous views.Dickson
