Its a capacitor bank .
Capacitor banks are used to compensate for the reactive loads which causes low power factor.In industries value below 0.9 are imposed with penalty.So for inductive loads and Harmonic compensation capacitor banks are connected to improve the Pf.
loads include
Ups
Inverters
Air conditioners
Motors
Arc furnaces etc
Kvar value for compensation can be found by
KW X correction factor
(calculate KW from your MD)

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?
