EST 1 Manual switching in three-phase circuits 230 V

Up to a certain power rating, multi-pole consumers can be connected directly in three-phase circuits. Suitable switching devices are available for this purpose and must be employed correctly for the application involved. The training topics are organised as follows:

  • Switching a three-phase induction motor with a squirrel cage motor on and off

  • Star-delta connection of a three-phase induction motor with a squirrel-cage rotor

  • Star-delta reversing circuit for a three-phase induction motor with a squirrel-cage rotor

  • Pole reversal with Dahlander three-phase induction motor

  • Pole reversal with a three-phase induction motor with two separate windings
