FUNCTIONAL PRINCIPLE
APPLICATION EXAMPLES
CI1(M)
“Tumbler” type operating mechanism.
Opening and closing operations are manually
or electrically performed with a speed
independent from the operator's action.
(Recharging time <= 10s at Un)
Feeder function equipment (set a net to
service or remove it from service) and
transformer fuse protection (load
protection through ISF fuses without
tripping). CI1M enables the ISF remote
switch operation.
CI2(M)
“Tumbler” type operating mechanism.
Equipped with stored-energy spring system
exclusively for opening. The closing
operation is followed by a recharge
operation that enables an eventual opening
operation in less than 100 ms through a
release magnet, a fuse or a push-button
Switch tripping by means of one or
more Fuses.
Switch tripping due to transformers
protection relays.
Switch opening.
CS1
Double function operating mechanism with
dependent operations for the SF switch and
independent operations for the cable
earthing switch (DC panels).
Enables the simultaneous control of two
SF switches (DB panels)
CST
Earthing switch operating mechanism.
Closing and opening speed are independent
from the operator’s action.
Enables the CD panel earthing
switchcontrol
