RCCB means residual current circuit breaker and MCB means
miniature circuit breaker.The difference between RCCB and
MCb is : RCCB Protects against residual leakage current.The
ratings are mentioed as 30mA,100 mA etc.But MCB only
protects against short circuit.

How two nos. 130 kw D.C motor get synchronise using D.C drive.
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?
