- Medium-voltage metal-enclosed load-interrupter switchgear, type Simosec overview
Medium-voltage metal-enclosed load-interrupter switchgear, type Simosec description
Simosec is medium-voltage metal-enclosed load interrupter switchgear up to 27.6 kV used mainly in the construction and industrial markets. It features a very small footprint of less than 15" wide and 48" deep, which significantly reduces the real estate cost. This space saving modular design makes it ideal for use in high rise buildings, hospitals, airports, wind-farms and industrial facilities, such as: automotive, food, petroleum and chemicals.
Medium-voltage metal-enclosed load-interrupter switchgear, type Simosec features
Features include:
For application on systems up to 63 kA 15 kV and 20 kA 27.6 kV
Extremely compact footprint
Meets ANSI/IEEE C37.20.3
UL- or C-UL Listing available
Seismic rated up to zone 4 (optional)
Ideal for utility, construction and industrial applications
Animated mimic diagram (mimic bus)
High switching capacity – 100 operations at 600 A – five times higher than ANSI requirements
High endurance – 1,000 mechanical operations
Gas-insulated three-position switch-disconnector, hermetically sealed for life inside a stainless steel vessel
No maintenance or adjustment required on the switch module over life of the switch
Switch 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
Integrated mechanical interlocking
High-voltage current limiting fuses and cable terminations accessible only if the feeder grounding switch is in the grounded position
Fuses and outgoing cables are front accessible, which means Simosec can be placed against the wall and maximize the use of available space
Convenient viewing window for verification of primary contact position (visible break)
Capacitive voltage indicators to show whether the cable side is energized or not are included as standard
Configurations: individual feeder switches, transformer primary switches and switch line-ups
Main bus at top or bottom to suit application
Over 20 years experience and more than 350,000 switch-disconnector units installed.
