Product Details
GN19-12 type disconnect switch is an indoor high voltage switching device widely used in 50Hz AC power systems with 12kV rated voltage. Mainly used to open and close circuits under no-load conditions to achieve reliable insulation between electrical equipment and power supply. It is divided into regular type (GN19-12) and wall type (GN19-12C), and supports three-phase parallel installation or wall installation in special scenarios.
Functions
Establish visible break points to ensure equipment and power isolation during maintenance.
Separation and closure of low-current circuits (such as bus charging current, voltage transformer excitation current).
Applicable scenarios
- Indoor areas such as substations and switchboards.
Locations not subject to fire, explosion, chemical corrosion or severe vibration
precautions.
- Working with the load is strictly prohibited: opening and closing must be done after the circuit breaker has been turned off.
- Maintenance requirements: Regularly check contact pressure, cleanliness of insulators and lubrication of mechanical components.
Thanks to the above design, the GN19-12 disconnector plays a key role in ensuring the safe operation of the power system. Specific selection should be based on current level, environmental conditions and functional expansion requirements
