Every body knows that ELCB ---> Earth Leakage Circuit
Breaker it itself indicate that whenever Current leaks and
go to Earth then it trip the circuit that called earth Leakage.
But where as RRCB Residual Cuurent .i.e sum of all Vector
sum is not equal to ZERO that is called Residual. Whcih
flows through the neutral, THis can set according to our
Load condition, that is it trip under Unbalnced currents.
Ir+Iy+Ib = In = 0 Noraml Condition
Ir+Iy+Ib NOt equal to ZERO, under unbalnced condition.

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?
