Main Components of SectosEarthing Switch
§ Integrated earthing switchfor NXB & NXBD type
§ Earthing Switch for safetymaintenance
§ Close-open-earthingoperations sequence, onlyearthing the switch whenSectos is opened
§ Mechanical endurance2000 CO
§ Earthing switch can only beoperated by manualoperation for safety reason
© ABB GroupOctober 30, 2014 | Slide 14
Main Components of SectosOperation Mechanism
§ Reliable manual and motor operation mechanism.
§ Independent spiral spring operation mechanism (no need
to charge the spring first)
§ Easy to be upgraded from manual operation to motoroperation at site
§ Operation mechanism box made from aluminum alloy
§ Spray painting of RAL7035, anti-corrosion, IP67

Main Components of SectosPosition Indicator
§ Large position indicatorsymbols
§ Reflective colours
§ Visible even at night
§ The reliable indication ofthe device meets thedesign and testing of IEC129 A2
© ABB GroupOctober 30, 2014 | Slide 16
Main Components of SectosGas Pressure Indicators
§ Temperature compensated gas density switch and gauge
§ Gas density switch: gas-low contact (NC) will open whenthe gas pressure is below 1.2bar, the alarm is then sent tothe relay
§ Gas gauge: under the tank, with large indication symbols.
© ABB GroupOctober 30, 2014 | Slide 17
Main Components of SectosGas Pressure Locking Devices
§ Optional gas-low locking device and manual locking device.
§ Gas-low locking device will lock the switch when gaspressure is below 1.1bar, the alarm contact (NC) will openand providing the signal to the relay
§ The switch will be completely locked when manual lockingdevice is active, and the motor control circuit is alsoautomatically disabled in the locked position
