Description

  • The magnetic contactors are a form of electrical relay found on most electrically powered motors.
  • They act as a go-between for direct power sources, and high-load electrical motors in order to homogenize or balance out changes in electrical frequency which may come from a power supply as well as to act as a safeguard.
  • It should be noted that though they are similar in design, magnetic contactors are not circuit breakers.
  • They do not sever the connection between appliance, and power source during a short circuit.
  • They are detachable from a motor so that an operator may work with that motor; disassemble or maintain it, without the possibility of live current still passing through the device.

Function

  • When electricity flows through the magnetic contactor, it causes the electromagnet to generate a strong magnetic field.
  • This field pulls the iron core into the coil, and creates an electrical arc.
  • Electricity passes in through one contact and into the contactors parent device in this manner.
  • To deactivate, the contactor can be physically pulled from the parent device.
  • Also, in the absence of electrical current, the spring pushes the core away from the coil, breaking the connection.
