GGD Fixed Low Voltage Switchgear Assemblies

The GGD type AC low-voltage distribution cabinet is suitable for power distribution systems with an AC frequency of 50Hz, a rated working voltage of 380V, and a rated working current of 5000A in power users such as power plants, substations, and industrial and mining enterprises. It is used for the conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment.

The product features high breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong practicality, novel structure, and high protection level. It can be used as an updated replacement for low-voltage switchgear assemblies. This product complies with the requirements of standards such as GB7251.12-2013 "Low-voltage Switchgear and Controlgear Assemblies" and IEC61439-2:2011 "Low-voltage Switchgear and Controlgear Assemblies".

● Ambient temperature: upper limit +40°C, lower limit -15°C (with special processes, it can reach -45°C);
● Altitude not exceeding 2500m (with special processes, it can reach 4000m);
● Relative humidity of surrounding air not exceeding 50% at the highest temperature of +40°C;
● Higher relative humidity is allowed at lower temperatures (e.g., 90% at +20°C). The impact of occasional condensation due to temperature changes should be taken into account.
● The inclination of the equipment installation to the vertical plane should not exceed 5%.
● The equipment should be installed in a place free from severe vibration and shock, and where the electrical components will not be corroded.
● Special requirements from users should be negotiated with the manufacturer.
