Product Details
GN19-12C type disconnect switch is an indoor feed-through wall mounted high voltage switchgear, widely used in 50Hz AC power systems, rated voltage 12kV. It is mainly used for switching circuits under no-load conditions to achieve reliable isolation between electrical equipment and power supply. It supports three-phase parallel installation or wall installation in special scenarios
functions
- Set visible break points to ensure equipment and power isolation during maintenance.
- Separation and closure of low-current circuits (for example, bus charging current, voltage transformer excitation current).
Applicable scenarios
- Indoor areas such as substations and switchboards.
- Places where there is no fire, explosion, chemical corrosion and strong vibration.
precautions
- It is strictly forbidden to work with the load: 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 GN19-12C type 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.
