Frequently Asked Questions
Q
What is the rated voltage of the GN19-10C series disconnector?
All models in the GN19-10C series — including the 400A, 630A, 1000A, and 1250A variants — operate at a rated voltage of 12 KV, making them suitable for medium-voltage power distribution systems.
Q
What is the maximum dynamic current the GN19-10C series can withstand?
The highest dynamic current rating in the GN19-10C series is 100 KA, available on the GN19-10C/1250-40 model. Other models are rated at 31.5 KA, 50 KA, and 80 KA respectively.
Q
What does the 4-second thermal stability current rating mean?
The 4-second thermal stability current indicates the maximum fault current the disconnector can carry for 4 seconds without sustaining thermal damage. For example, the GN19-10C/1250-40 has a 4s thermal stability rating of 40 KA.
Q
How do I select the correct GN19-12 model based on installation dimensions?
Refer to the Dimension table and drawing provided above. Each product number (e.g., GN19-12/400, GN19-12/630) has specific A, B, and C dimension values (in mm) along with mounting hole configurations, allowing you to match the product to your panel or switchgear requirements.
Q
What is the difference between the two sets of dimensions listed for each GN19-12 model?
The two sets of dimensions (A, B, C) shown in the dimension table correspond to different installation configurations or orientations for the same model. Please refer to the dimension drawing image above to identify which configuration applies to your specific installation scenario.
Q
Are the GN19-10C disconnectors suitable for indoor use?
Yes, the GN19-10C series indoor high-voltage disconnectors are designed for indoor medium-voltage switchgear applications. They are commonly used in power plants, substations, and industrial distribution systems operating at 12 KV.
