The line contactor must be sized in AC-3 category with a current greater or equal to the motor full load current (FLC). Example Motor rated current = 28 A Soft starter rated current ≥ 28A AC-3 (e.g. ADXL0030600 à 30A) Line contactor ≥ 28A AC-3 (e.g. BF3200A230 à 32A AC-3) [...]
Bypass contactor should be AC-1 rated for the motor full load current (FLC) because it does not carry the starting current. ______________________________________________________________________________________________ Other information on this topic Visit the website page dedicated to contactors.

The command of the line contactor is managed automatically by the soft starter with a relay output programmed with the function LINE.CONT (sometimes also called Run according to soft starter models): LINE CONT. = the output closes at the start command and it remains closed all the time when the soft starter is feeding voltage [...]
Yes, it can be used circuit breaker with undervoltage trip. In case of fault the soft starter will interrupt the signal on the breaker undervoltage trip through a relay output, with consequence interruption of the current flow to the motor. But contactor it is preferable due to its high mechanical durability compared with circuit breaker which [...]
It is a contactor installed upstream the soft starter to warrant a galvanic separation between the power supply line and the motor when the motor is not in use (stop). The presence of the line contactor is extremely important for the following purposes: 1.Safety of the personnel: it removes the voltage on the motor side [...]
