Product Overview:

SAFESAVE SJR3-3000 series 660v has a built-in bypass motor soft start and integrated bypass contactor, which greatly reduces the construction cost of the application. The rated power is from 30kW to 355kW. It is different from the installation and wiring maintenance of the external soft start, which is different from the conventional 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.

Electrical parameters of SJR3 series softstarter

Three-phase power supplyVoltage(AC) 380V±15%(220V and 660V optional)
Frequency 50Hz/60Hz
Applicable motorSquirrel cage three-phase asynchronous motor
Starting frequency When the motor is fully loaded, it shall not start more than 4 times per hour;
Less than 10 times per hour with no or little load
Protective classIP20
Anti shock Accorded with IEC68-2-27:15g, 11ms
Seismic capacityVibration intensity is 0.5G or less at an altitude less than 3000 meters
Ambient temperatureThe capacity needn't be reduced when the working temperature is between 0℃ and
40℃(At the temperature between 40℃ and 60℃, the current should be decreased 2% whenever the temperature is 1℃ higher.)
Storage temperature-25℃~70℃
Ambient moisture93% no condensation or drip, in line with IEC68-2-3
Maximum working The capacity will not be reduced when the working height is less than 1000 meters( If
is higher than 1000 meters, the current will be decreased 5% whenever it is 100 meters higher.)
Cooling means Natural cold wind

Special Tips:

All soft starting products are of device types in case of delivery. In order to make it convenient for installation and debugging of the set manufactures, the output protection of the device-type soft starter has been set as"standard when delivery. In installation and debugging, the set manufacturer can directly use a small motor or use three lamps to form a star to work as the load. then starting. stop, control and other operations can be conducted. However. In practical application, please be sure to change the output protection to"advanced, and then the soft starter will possess the complete protection functions for phase loss, three-phase unbalance, over-current, overloading and so on.

Note: If the soft starter is reset to factory defaults, the output protection will be reset to"standard again, so it will be necessary to set the protection level to"advanced"again ). Please kindly note this.
