Frequently Asked Questions

Q What is the rated voltage of the GN19-10C series indoor high-voltage isolating switch?

All models in the GN19-10C series operate at a rated voltage of 12 KV, making them suitable for medium-voltage indoor switchgear applications up to 12 KV systems.

Q What rated current options are available for the GN19-10C isolating switch?

The GN19-10C series is available in four rated current options: 400 A, 630 A, 1000 A, and 1250 A, allowing flexible selection based on your circuit load requirements.

Q What is the maximum dynamic current capacity of the GN19-10C series?

The highest dynamic current capacity in the series is 100 KA, offered by the GN19-10C/1250-40 model, which also supports a 4-second thermal stability current of 40 KA.

Q How do I select the correct model based on the dimension table?

The dimension table provides key measurements A, B, and C (mounting hole configuration) for each product number. Match your panel or switchgear mounting space with the appropriate GN19-12 model to ensure proper installation fit.

Q What does the 4s thermal stability current parameter indicate?

The 4-second thermal stability current indicates the maximum fault current the switch can withstand for 4 seconds without sustaining damage. This is a critical parameter for short-circuit protection design in power distribution systems.

Q Is the GN19-10C isolating switch suitable for indoor use only?

Yes, the GN19-10C series is specifically designed for indoor high-voltage applications. It is intended for use in indoor switchgear panels, substations, and distribution equipment where controlled environmental conditions are maintained.
