Sakelar Pemutus Tegangan Tinggi Dalam Ruangan GN19-12 12kV

GN19-12 series disconnect switches are suitable for AC 50/60Hz indoor power systems with rated voltage up to 12kV.

The switch is equipped with a CS6-1 manual operating mechanism and is widely installed in switchgear panels, substations, and industrial distribution systems.

The product is designed to:

• provide safe electrical isolation,
• ensure visible disconnection during maintenance,
• improve operational safety,
• support reliable medium-voltage switching systems.

Variants include:

• standard type,
• wall-through type (GN19-12C),
• anti-pollution type,
• high-altitude type,
• live display type.

Main Features

• Rated voltage: 12kV
• Indoor installation type
• Manual operating mechanism (CS6-1)
• Compact and simple structure
• Large insulation clearance
• Stable operation and long mechanical life
• Optional wall-through installation type
• Reliable visible isolation point
• Maintenance-free design
