What is IGBT?Where it is used? What is the difference
between IGBT and Thyristor?
Answer Posted / shishant anand
IGBT are widely used in medium power application such DC and
AC motor drive. IGBT is more expensive. The IGBT Of 1200 v,
500A rating 0.25 to 20 micro second turn off time with
operation frequency upto 50Khz are available.

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?
