Answer Posted / wareagle
Skin effect is the tendency of an alternating electric
current (AC) to become distributed within a conductor such
that the current density is largest near the surface of the
conductor, and decreases with greater depths in the
conductor. The electric current flows mainly at the "skin"
of the conductor, between the outer surface and a level
called the skin depth. The skin effect causes the effective
resistance of the conductor to increase at higher
frequencies where the skin depth is smaller, thus reducing
the effective cross-section of the conductor. The skin
effect is due to opposing eddy currents induced by the
changing magnetic field resulting from the alternating
current

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?
