Working Mechanism

  • They use a rotating armature that moves between stationary contacts to open and close the circuit.
  • The rotating armature is driven by an electromagnet which energises or de-energises to control the flow of current in the circuit.
  • When the electromagnet gets energised, the armature rotates and the contacts close to allow the flow of current.
  • When the electromagnet is de-energised, the armature returns to its original position and the contacts open to interrupt the flow of current.

Features

  • Eaton counter rotary contactors can handle high inrush currents for motor starting applications.
  • They feature 10:1 pulses per revolution and can be operated without any power source.
