Brief Introduction

 

Soft starter 380V is non-full-voltage start, also known as under-voltage start. Hard start is full-voltage start, for large loads of electrical appliances, the instantaneous current is very large when starting, which is not only a high demand on the starting equipment and the impact on the circuit is also very large, so the large equipment always adopt soft start mode.

 

Soft starter 380V is not full-voltage start, also known as under-voltage start. Hard start is full-voltage start, large loads of electrical appliances start instantaneous current is very large, which is not only high requirements for starting equipment and the impact of the circuit is also very large, so the large equipment is usually used in a soft start way, take the AC three-phase motor as an example: the simplest and most practical is the star-angle start way, that is, using a contactor to switch the motor at the start of the star connection to the power supply, because of the large motor windings are mostly triangular connection, connecting the star after its line current becomes Star after the line current into a phase current (reduced by 1.414 times). Therefore, the starting current is greatly reduced, when the motor is running and then automatically switched from the star into the angle on the completion of the soft start. Soft starter 380V protects not only the motor, but also the circuit, as well the equipment.
