Answer Posted / poonam
Vector Groups are made especially to make out difference in
the connections. The connection can be delta(D) or star(Y)
The number after that indicates the phase difference
between the primary and the secondary voltage.
e.g.-> Y11 means transformer is star connected with
secondary voltage leading the primary voltage by 30 degrees.
I am not sure of the effect of phase displacement in
transformer

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
