Scope of application:
GGD AC low voltage distribution cabinet is suitable for power plants, substations, industrial and enterprises and other power users as an AC 50Hz, rated working voltage 380V, rated current up to 6300A distribution system for power, lighting and distribution equipment conversion, distribution and control of electrical energy. This product has high breaking capacity, a rated short-time withstand current of up to 50kA, flexible circuit design, convenient combination, strong practicality, and innovative structure. This product is one of the representative products of assembled and fixed panel switchgear in China.
This product complies with standards such as GB7251.12-2013 "Low voltage switchgear and control gear" and IEC60349 "Low voltage switchgear and control gear".
Model and its meaning:
Normal usage conditions:
Environmental temperature: -50¡æ¡«+40¡æ, and the average temperature within 24 hours does not exceed+36¡æ.
Altitude: not exceeding 2500m
Relative humidity: not exceeding 50% when the ambient air temperature is+40 ¡ã C.
At lower temperatures, there can be higher relative humidity (such as 90% at+20 ¡æ). Considering the temperature changes, moderate condensation can be generated. When installing equipment, the inclination with respect to the vertical plane should not exceed 5 ¡æ
The equipment should be installed in a place without severe vibration, impact, and corrosion.
Note: If the above conditions cannot be met and the user has special requirements, they can negotiate with our company to resolve them.
