In most cases, the contactor does not simply wear out from normal use. Though their output is used for switching very high loads, they are controlled by a circuit with very less power. Contactors are used in applications ranging from the light switch to the most complex, automated industrial equipment. Whatever the application, the function of the contactor is always the same: to make and break all power supply lines running to a load. In general contactors are intended to control higher levels of current. Namskar, Thanks for your valuable information.
