Contactor Circuits in Three-phase Systems
As of a certain power rating, direct switching of three-phase loads becomes impossible. For this reason, such loads are switched indirectly by means of contactor circuits of many different kinds. The development of a control system and installation with functional control are the key points of this unit. The supplementary sets allow additional control exercises with more complexity to be implemented. The supplementary machine set includes all the necessary machines and equipment for testing direct and indirect control of motors in three-phase circuits.

Note:
This Training System is a Basic Equipment Set.
