Control and Protection Zhongkai Kaibao Xinling Control and Protection Switch Electrical Guojia Guojia Ouyi Factory Direct Sales Price Control and Protection Jiangsu Yuantai Jiangsu Kailong Shanghai Jiayi Basic Fire Isolation and Pressure Reducing Resistor Star-Delta Leakage
Mainly used in power systems with AC rated voltage to rated current, capable of connecting and breaking currents under normal conditions including specified operating overload conditions, and capable of connecting and breaking currents under specified abnormal conditions. Current, such as short-circuit current.
Adopting a modular single product structure, it integrates the main functions of traditional circuit breakers (fuses), contactors, overload (or overcurrent phase failure), relays, starters, isolators, etc., and has remote automatic control and on-site service. It has direct human control function, panel indication and electromechanical signal alarm function, and coordinated time current protection characteristics (inverse time limited time limit and instantaneous three-stage protection characteristics). By selecting functional modules or accessories as needed, you can control and protect general (infrequent starting) motor loads and motor load distribution circuit loads that are frequently started

Working conditions
Ambient air The upper limit value of temperature does not exceed ℃
The lower limit value does not exceed ℃
The daily average value does not exceed ℃
When the ambient air temperature exceeds the above range, special settings must be made at the factory
The altitude of the installation site does not exceed meters
Atmospheric conditions
The relative humidity of the atmosphere does not exceed the ambient air temperature of ℃. Higher
relative humidity can be achieved at lower temperatures. When the monthly average minimum temperature is ℃, the average maximum relative humidity of the month is, measures must be taken to prevent condensation on the product due to temperature changes
Pollution level
Installation category III (system) IV (System)
The control power supply voltage should be within the fluctuation range of (~)
