SIMOSEC (Siemens)
MOSEC switchgear is a factory-assembled, typetested, three-phase, metalenclosed, indoor switchgear according to IEC 60 298 and VDE 0670 part 6 for single busbars systems.
Technical data:
- Rated voltages up to 24 kV
- Rated short-time withstand current up to 25 kA
- Rated normal current of feeders
- Up to 630 A, e.g. for ring-main, metering and circuit-breaker panels
- Up to 1250 A, for circuit-breaker and bus sectionalizer panels
- Rated normal current of busbar up to 1250 A
Typical uses
SIMOSEC switchgear is used for power distribution in distribution systems with feeder currents up to 630A.
Modular space-saving design allows use in
- Substations, customer transfer substations, distribution substations and switching substations of power supply and public utilities

Personal safety
- All switching operations can be performed with closed panel front • Metal-enclosed LSC 2 A or LSC 2 B panels
- HV HRC fuses and cable sealing ends are only accessible when the outgoing feeders are earthed
- Logical mechanical interlocking
- Capacitive voltage detection system for verification of safe isolation from supply
- Earthing of outgoing feeders by means of make-proof earthing switches
Â
Busbar compartment
- Busbar
- Insulating cap (e.g. for Ur > 17.5 kV) on busbar
- Bushing-type insulator for busbar
Security of operation
- Components, e.g. operating mechanisms, three-position switches, vacuum circuitbreakers proven for years
- Panels (metal compartmentalization (metal-clad) between busbar and switching device and between switching device and cable connection compartment)
- panels with metal compartmentalization between switching device and Cable compartment
- Three-position switch metal enclosed with gas-insulated switching functions
