Performance characteristics
Soft start function: Through the use of voltage reduction and other technical means to achieve the smooth start of the motor, to avoid the starting current on the power grid and the motor itself caused a large impact. Effectively reduce the starting current, reduce the impact on the power grid, so that the power grid and mechanical system can be protected, while avoiding the mechanical shock when the motor starts, protect the motor and load.
Bypass operation: After the start is completed, the bypass contactor will be triggered by the internal signal, so that the main circuit current flows from the thyristor bypass to the bypass contactor loop, and the soft starter exits the operation, which can extend the life of the soft starter, and avoid harmonic pollution in the power grid, and also reduce the thyristor heating loss in the soft starter.
A variety of protection functions: usually with overload protection, phase loss protection, overheat protection and other functions, can effectively protect the motor and soft starter itself from damage under abnormal conditions.
Application field
It can be widely used in metallurgy, petrochemical, water treatment, food and health products processing, mining and machinery industries, suitable for all kinds of motor loads requiring smooth start, such as pumps, compressors, lifts, elevators, short-distance conveyor belts and bow thrusters.

Compare with other soft starters
Advantages: Compared with traditional star-triangle and autobuck starters, the SEG 300 bypass soft starter has better starting performance, smoother starting process, less impact on the power grid and the motor, and more complete protection function. Compared with the on-line soft starter, the bypass soft starter has the advantages of good energy saving effect and multi-motor linkage control.
Disadvantages: Compared with some high-end smart soft starters, the SeG 300 May be slightly inferior in terms of communication functions and intelligence, for example, it may not have a variety of fieldbus communication protocols and remote monitoring functions as some soft starters do.
