This GN24-12D high-voltage disconnect switch is an indoor high-voltage disconnect switch with a grounding switch. It is an upgraded version of the GN19 series (with added grounding function). Its core function is "no-load switching + safety grounding" in 12kV power systems, making it a combined safety isolation and grounding device in power distribution systems. This high-voltage disconnect switch has a rated voltage of 12kV and a rated current of 630A/1000A/1250A (common specifications). It is suitable for installation in indoor switch cabinets, substations, and factory power distribution rooms, especially in scenarios where grounding is required for maintenance (such as transformer inlet terminals and busbar sections), replacing the combination of "disconnecting switch + separate grounding switch" and saving space.

Structural form

Flat-mounted type (GN24-12D): Main blade + single-sided grounding blade;
Through-wall type (GN24-12CD): With through-wall bushing, suitable for through-wall installation of switchgear;
Double-sided grounding type (GN24-12SD): Both moving and stationary contacts can be grounded, suitable for complex power distribution scenarios.

Prohibited Actions:

* It is prohibited to open or close the main contact under load;

* It is prohibited to forcibly disengage the interlocking device;

* It is prohibited to close the main contact while the grounding switch is closed.

Note:

Different manufacturers' derivative models (such as anti-fouling type, high-altitude type) may have slightly different dimensions. It is recommended to refer to the original installation drawings that come with the equipment. If you need detailed CAD drawings, you can ask us for the "GN24-12D outline and installation dimension drawing".

Installation environment requirements

Indoor installation, ambient temperature -25℃ to +40℃;

Relative humidity ≤90% (anti-fouling type can be used in high humidity/pollution environments);

Mounting surface (switch cabinet beam/bracket) must be flat, load-bearing capacity ≥60kg (equipment weight approximately 50kg).

FAQ：

Q:What is the short-time withstand current (4s)?

A: 40kA(1250A for example)

Q: Does this disconnect switch have anti-misoperation features?

A: Yes, they come with mechanical interlocks to prevent "grounding while energized" and "closing the switch while grounded," which complies with power safety regulations.

Q: How long have you been manufacturing electrical products?

A: 10+ years. From the start, we do metal accessories then assemble all parts to final product.

Q: What should I do if I receive a damaged or defective product?

A: Please contact us immediately. We will find out the cause and do our best to make up for the loss.
