GN24-12D Indoor High-Voltage Disconnecting Switch

The GN24-12D series indoor high-voltage disconnecting switch is designed for power systems with a rated voltage of 10kV and a frequency of 50Hz. This device is primarily used for isolating and disconnecting circuits under no-load conditions. It is suitable for indoor installations and provides reliable circuit switching operations. The device is designed for high adaptability and reliability, ensuring safe operation in harsh environments.

A. GN24-12D(11.2:111.2)Q Type: Features grounding on the moving (or stationary) contact side. The main knife and grounding knife are integrated into a single frame. Type 1 is left-side operated; Type 2 is right-side operated. The Q-type is a full-duty product and can be equipped with a voltage presence indicator per user requirements.

B. GN24-12SD1、1(C1.2.3) Type: Grounding on both moving and stationary contact sides. The moving (or stationary) contact side can be modified to a wall bushing (or both sides can use wall bushings). The main knife and two grounding knives are combined on the same frame. One grounding knife can be operated independently or simultaneously via a single mechanism.
