  What is Contactor? The contactor is an electrically controlled switching device. It is used for electrical switching. The basic operation of this is often almost like a relay, but the sole difference is that contractors can carry large current compared to relay up to 12500A. They cannot provide short or overload protection but can break the contact when coil excites. Circuit Diagram of Contractor A contactor is one among the most circuit parts, which may stand on its own power control device or a neighborhood of a starter. They are wont to connect and break power supply lines running through power lines or repeatedly establish and interrupt electric power circuits. These are utilized in light loads, complex machine control. They are used with motors , transformers , heaters. It are often considered as an intersection between the negative feedback circuit and power circuit because it's controlled by the negative feedback circuit , it also controls the circuit between power and
