Core units
Disconnecting switch
SV6 - General purpose
PM100011
The SV6 core unit is a “3 in 1” device combining
the functions of a load break switch, disconnector
and associated earthing switch. It can be used in
various functional units.
bb3 positions (closed, open & disconnected,
earthed) with direct earthing of cables
bbIntuitive operation and clear mimic panel
indications
bbBuilt-in positive interlocks between main switch
and earthing switch.
Basic equipment
bbTotally insulated and screened core unit integrating load breaking, disconnection
and earthing functions.
bbMain switch
vvvacuum disconnecting load-break switch providing both load breaking and
disconnection functions
vvanti-reflex lever-operated mechanism (CIT type), independent of operator action.
bbEarthing switch
vvcombined with the main switch
vvfully and positively interlocked with the main switch
vvair technology in sealed-for-life tank at atmospheric pressure
bbTotally SF6-free solution based on vacuum and air breaking technologies.
Accessories
Locking
bbStandard built-in padlocking facility for main switch, earthing switch and interlock
(shackle diameter < 9 mm)
bbOptional keylocking facilities with flat or tubular key types:
vv1 or 2 keylocks for main switch in “open & disconnected” position
vv1 or 2 keylocks for earthing switch in “cables earthed” position
Interlocking
bbStandard built-in interlock between main switch and earthing switch
bbOptional interlock between cable box door and earthing switch (prevents opening
of the door unless the earthing switch is in “cables earthed” position) (*)
bbOptional interlock between main switch and cable box door (prevents closing of
the main switch when the door is open) (*) .
Auxiliary switches
bbFor main switch:
vvstandard: 2 changeover contacts (1 when electrical operation)
vvoptional: up to 2 additional blocks of 4 changeover contacts.
bbFor earthing switch:
vvoptional: 1 changeover contact.
Operation counter
bbOptional for main switch.
