Generally speaking, a contactor is activated by a control input which is a lower voltage / current than that

43、 which the contactor is switching. Contactors come in many forms with varying capacities and features.Contactors vary from having a breaking current of several amps ,thndwotdl volts to thousands of amps and many kilo-volts. The physical size of contactors differs from a few inches to the size of a s

44、mall car.A. to make with a penB. to keep away fromC. to pullThen let s know the purpose of contactor. Usually, contactors areused to control electric motors, lighting, heating, capacitor banks and other electrical loads.And now let ssee what a contractor consists of. We can say: a contactor consists

45、 of 3 different systems: contact system, electromagnet system and arc control system.So do you know their function? In a general way, the contact system is the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. The electromagnet system prov

46、ides the driving force to close the contacts.FuseMaybe you have already known that a fuse is the easiest and efficient protective electrical apparatus and it is designed for short circuit protection in many cases.
