could u tell me the purpose of using contactir instead of Vd4 circuit breaker for example ?

[@rickantonio188]

Hi Haddou, depending to the contactor used, there are so many types of contactor. If you mean, the ordinary contactor compared with VD4 (Vacuum or Air Circuit Breaker). For ordinary contactor mostly used for low voltage, meanwhile for Vacuum or Air Circuit Breaker used for medium and high voltage. Because of the arc (spark) generated during contactor touching each other or during pulled apart, in low voltage the arc (spark) is not as much as medium or high voltage. The Vacuum Circuit Breaker able to extinguish the arc in shortest time, compared with Air Circuit Breaker or ordinary breaker.
