General
The main function of the built-in bypass soft starter is to reduce the pressure on the motor during startup by controlling the voltage and current changes, thereby increasing startup ef- ficiency and extending the motor's lifespan.
The built-in bypass soft starter typically includes bypass contactors and control power supplies, enabling a smooth transition to bypass mode during startup to prevent the motor from experiencing excessive current and voltage shocks.
