Connection of motor protector
NOTE!
The thermal contacts in the winding are CSA approved only for 250 V and below.
For other voltages when CSA approval is required a transformer is used to reduce
the voltage over the thermal contacts.
As a consequence the transformer has to be disconnected when the connection is
changed from 440-460 V Yser to 220-240 V Y// .
If the change is done from 220-240 V Y// to 440-460 V Yser the transformer has
to be connected.
