Just as diverse as the different forms and designations
with the asynchronous motor is the
diversity of the respective motor feeders for
start-up and control. To facilitate a simplified
overview, the four most well-known and
important motor feeders are examined in the
following. A three-phase AC current incoming
mains supply earthed as the neutral point
(3 / N / PE / AC 50/60 Hz) is assumed.
Eaton Moeller offers a complete range on the
motor feeders for switching, protection and
control of three-phase asynchronous motors for
the entire range of start variants shown here.
