|---|---|
The GN19-12 series indoor high voltage disconnect switch is designed for a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used in indoor power distribution equipment for isolating power sources under no-load conditions.
This disconnect switch is not suitable for installation environments with explosive, corrosive, or conductive gases, or areas with severe vibration that may affect insulation and conductivity.
Rated Voltage: 12kV
Rated Current: 400A, 630A, 1000A, 1250A
Installation Type: Standard & wall-through types (C1, C2, C3)
Structure: Conductive parts fixed by post insulators, with blade and static contacts
Operation: Linked with C56-1 (or C57) manual/mechanical operating mechanism
Contact System: Blade and static contacts with spring pressure for reliable conductivity
Stability: Enhanced thermal and dynamic stability with magnetic lock plate (for 1000A & 1250A models)
High mechanical strength with double-blade copper structure
Low temperature rise due to increased heat dissipation area
Strong contact pressure ensures reliable electrical performance
Enhanced dynamic and thermal stability for high current ratings
Flexible wall-through installation options for different layouts
Altitude: ≤ 1000m
Ambient Temperature: -25°C to +40°C
Relative Humidity: ≤ 95% (daily average), ≤ 90% (monthly average)
Seismic Intensity: ≤ 8 degrees
Installation Site: Free of fire, explosive gases, severe pollution, chemical corrosion, and strong vibration
