This is installed in the branch point of below load capacity 8,000kVA of multiple earth neutral system 22.9kV-Y distribution system or in the service entrance of consumer. When over load or fault is occurred, minimizes the damage and prevent the fault expansion by breaking or opening exactly the fault section with the cooperation of protection device (CB, Recloser). Easy operation status monitoring is possible by built-in load current indicator and live line status distinction function. ASS is used for frequent lighting place, industrial line and has the following functions.

Key Characteristics
25.8kV gas insulated automatic section switch cooperates with upper stream device(CB, Recloser) to protect feeder from fault currrent. And when the fault current is more than over current [Lock current(800A), upper stream protection device removes a fault solid and sound. It is used for frequent lighting place and industrial zone line, and has the following function.
- Low pressure indication and Lock function
- Gas Release Device function
- Coefficient function
- Over Current Trip Function
- Over current Locking and Tripping function
- Inrush current restraint function
- Line current and hot line indication function
- Easy function setting(LCD menu)
- Battery over-discharge preventing function
