GENERAL

This product is designed to be compact, small in space, strong in insulation capacity, and easy to install and adjust. Its performance meets the requirements of High Voltage AC Disconnectors and Earthing Switches (GB1985-2004). It is applicable to indoor power systems with three-phase AC 50Hz, rated voltage 10V AC 50Hz, and below. It is used for opening and closing circuits under voltage and no load. It can be used together with the high-voltage switch cabinet or separately.

MODEL AND MEANING

USAGE: ENVIRONMENTAL CONDITIONS

1. Altitude: Not more than 2000m. 
2. Ambient air temperature: maximum  +40ºC, minimum - 10ºC, daily temperature difference 25.
3. Humidity: daily average relative humidity ≤ 95%, monthly average relative humidity ≤ 90%.
4. Places without serious dust, chemical corrosion, and explosive substances.
5. Places without frequent severe vibration.

MAIN ADVANTAGES

This product is a new type of rotary contact disconnector. Its main structure is to fix two groups of insulators and contacts on the upper and lower planes of the three-phase common low frame. Through the rotary contact, the switch can be closed and opened.

The switch is an open type with grounding power added to the GN30-10 switch, which can meet the requirements of different power systems.
