CONTACTOR

A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings. It is used primarily to control electrical devices such as motors, lighting, heating, and other electrical loads. The contactor is operated by a control circuit, which is typically a lower voltage and current than the main power circuit. When the control circuit is energized, the contactor's coil is magnetized, creating a magnetic field that pulls in the contacts, completing the power circuit and allowing electricity to flow. This makes contactors essential components in various industrial and commercial applications for automating and controlling electrical systems.
