Contactor 2 Poles 230V NO
A contactor is an electromechanical element with the capacity to establish or interrupt the electric current. The contactors have the possibility of being remotely operated by an external element, which allows us to operate an electrical device with a large load from small switches, remote controls or devices, without these having to bear the load of the device we want to activate
NO or normally open contactors are devices that, as long as they are not operated, do not allow the passage of current to the device they supply
