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 connect.
