Answer Posted / ravi
RCCB-Residual current circuit breaker.This is used in
Industrial safety purpose i.e. is to isolate the healthy
circuit whenever earth fault & overload current occurs.we
have in market at different type of ratings 30ma,100ma.as
per requirement will use above ratings.for example human
body having current flowing capacity of 30ma.so in
industrial as per safety constraint they will prefer 30ma
RCCB/ELCB.

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?
