Product Overview:

The SJR3-3000 series has a built-in bypass motor soft start and integrated bypass contactor, which greatly reduces the construction cost of the application. It is different from the installation and wiring maintenance of the external soft start. It is also different from the high heat conflict of the thyristor online soft start. This series also supports the bus function of Modbus protocol to support large-scale industrial control layout.

Product Features:

1. Anti shock: Accorded with IEC68-2-27: 15g, 11ms

2. Seismic capacity: Vibration intensity is 0. 5G or less at an altitude less than 3000 meters.

3. Ambient temperature: The capacity needn't be reduced when the working temperature is between 0℃ C and 40℃ ( At the temperature between 40℃ and 60℃, the current should be decreased 2% whenever the temperature is 1℃ higher. )

4. Storage temperature: -25℃~70℃
