1. A electrical contactor, comprising:
separable contacts that include a first pair of mating contacts and a second pair of mating contacts, wherein the second pair of mating contacts are initially separated from the first pair of mating contacts;
a first portion of the electrical contactor that includes the first pair of mating contacts and a solenoid plunger that is configured to receive a plunger rod;
a second portion of the electrical contactor that includes the second pair of mating contacts, wherein the plunger rod is configured to be inserted within the solenoid plunger and rotated towards the second portion, wherein upon a requisite rotation of the plunger rod, the plunger rod is threaded into the second portion of the electrical contactor and enables the second portion of the electrical contactor to be pulled up towards the first portion of the electrical contactor, wherein the second pair of mating contacts are configured to move closer to the first pair of mating contacts until the second pair of mating contacts mate with the first pair of mating contacts to increase a wear allowance to a predetermined desired level.
