- The rated power and rated current indicate the maximum rated value of the soft start. The matching specification of breakers and bypass contactors should match with the motor.
- Soft starter is for six terminal inputs and three terminal outputs, it is still with the online protection function at the state of bypass contactor sucking, do not need to add additional motor protection device.
