The series control and protection switching appliance integrates control and protection functions and is equivalent to a circuit breaker (fuse), contactor, overload relay auxiliary appliance. It well solves the problem of protection and control characteristic matching between components that cannot or is difficult to solve with separate components, making the protection and control characteristics more perfect and reasonable (it has inverse time limit and instantaneous three-stage protection characteristics as long as it is based on the load power or current You can correctly select a single product to replace the previous various electrical appliances from the power incoming end to the load end without reducing the capacity, which greatly reduces the designer's workload.
It has operational reliability and continuous operation performance of the system. It can be put into use without maintenance and has the continuous operation performance after breaking short-circuit fault. After the breaking short-circuit current test, it still has an electrical life of not less than 2 times. This is difficult to achieve in a system composed of separate components such as circuit breakers. The characteristics have greatly improved the operational reliability and continuous operation of the system. Among them, the index is the internationally leading and the highest domestic index for similar products.
Energy-saving and material-saving, small size, small installation area, no separate component contacts, reducing line heating. It has the advantages of saving energy and materials.
Compared with plastic case circuit breakers, it has the characteristics of high breaking capacity and short arcing distance. The short circuit breaking capacity reaches high during rated operation. The breaking type is the standard type and the economic type is under the expected short circuit current. The breaking time is only the current limiting coefficient reaching the leading level of the molded case circuit breaker and the current limiting level of the fuse, which greatly limits the dynamic thermal impact of the short-circuit current on the system. The arcing distance is only.
With protection settings Both the thermal trip (inverse time limit) current and the magnetic trip (definite time limit) current with adjustable current characteristics can be adjusted on the panel, that is, in addition to the conventional thermal protection current that can be set according to the load power, the overcurrent protection setting current It can also be adjusted on the panel (the adjustment range of the distribution load is 0.000000000000000000000000000-case circuit breaker). It overcomes the shortcoming that the user cannot adjust the short-circuit protection setting current of the molded case circuit breaker after leaving the factory
Working conditions
The upper limit value of ambient air 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

Precautions
Equipment installation requirements
To ensure the accuracy of the protection characteristics, the installation of connecting wires should comply with regulations. Before use, carefully check the coil voltage and accessory control power supply voltage. Correct and consistent to avoid damage. The operating knob should be able to operate normally. The electromagnet should attract the operating knob and turn it to the position where the electromagnet is released. Its mounting surface allows for left and right rotation relative to its axis.
If it is in the tripped state (both rotated in the position), the knob should be turned to the re-locked position and then turned to the position to achieve remote control.
It should not be exposed to wind and rain during transportation and storage before use. Place it in a warehouse where the daily average relative humidity is not greater than (at ℃, the ambient temperature is not higher than ℃ and not lower than ℃
Setting and operation
Before operation, the user should set the parameters for air parameter operation (in the motor When starting and running, pressing the setting key is invalid. Press the setting key to select the setting type. Press the shift key in sequence to select the data shift. Press the data key to modify the data. After setting a certain parameter, press the setting key to enter the next setting status value. Unnecessary options should be abandoned at the end. After setting all parameters, press the reset key to exit the setting state.
