what is pressure relief valve?where it is used????
Answer Posted / swapnil pawar
Pressure relief valve is used were air pressure is
maintained .It is pressure relief valve which maintains
pressure.
For e.g.
If in air cylinder 10kg air pressure is maintained, then if
by chance air pressure increases to 11kg the Pressure
relief valve get activates and 1kg pressure release.
This is used for safety reason.

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?
