The starting current, will be 6-8 times higher than the
motor's rated current because the motor is at rest.
Those starters reduce or diminish this inrush starting
current are called electrical soft starters.
Soft start is one of the facilities available in VVVF
drives. The other facilities are providing higher starting
torque, speed variation, constant torque maintenance soft
stop etc. Simply saying VVVF drive take care of starting
control, speed control, protection control, forwarding,
reversing control and stopping.

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?
