15. OPERATION
All switches can be operated with the included operating
handle.
Internal mechanical interlocking between the switch discon-
nector/isolator and the associated earthing switches pre-
vents incorrect operation. For detailed interlocking descrip-
tion, see dedicated overview for each module in catalogue
1VDD006104 GB.
The operation of the switch disconnector/circuit-breaker and
earthing switches can be further interlocked by means of a
padlock.
The earthing switches are operated by a snap action
mechanism, which ensures fast closing. The earthing switch is
closed by turning the operating handle clockwise. Turning the
operating handle anti-clockwise opens the switch.
An anti-reflex system, standard on all operating handles,
prevents the immediate re-operation of switches.
