Medium-voltage, metal-enclosed,
load-interrupter switchgear
nNo maintenance or adjustment required
on the switch module over life of the
switch
nSwitch disconnector combines the
function of a load-interrupter switch
(with closed-open indication) and a
grounding switch (with open-ground
indication), thus inherent design offers
additional safety for the operators
nIntegrated mechanical interlocking
nHigh-voltage current limiting fuses and
cable terminations accessible only if
the feeder grounding switch is in the
grounded position
nFor application on systems up to 63 kA
15 kV and 20 kA 27.6 kV
n Extremely compact footprint
nMeets ANSI/IEEE C37.20.3
nUL- or C-UL Listing available
n Seismic rated up to zone 4 (optional)
nIdeal for utility, construction and
industrial applications
nAnimated mimic diagram (mimic bus)
nHigh switching capacity –
100 operations at 600 A – five times
higher than ANSI requirements
nHigh endurance – 1,000 mechanical
operations
nGas-insulated three-position switch
disconnector, hermetically sealed for life
inside a stainless steel vessel
nFuses and outgoing cables are front
accessible, which means Simosec can be
placed against the wall and maximize
the use of available space
nConvenient viewing window for
verification of primary contact position
(visible break)
nCapacitive voltage indicators to show
whether the cable side is energized or
not are included as standard
nConfigurations: individual feeder
switches, transformer primary switches
and switch line-ups
nMain bus at top or bottom to suit
application
nOver 20 years experience and more
than 350,000 switch-disconnector units
installed
Type Simosec, up to 27.6 kV, 1200 A, 25 kA up to 15 kV and 20 kA at
27.6 kV, 125 kV BIL
