Answer Posted / sasi karthick a
MCB is for lower voltage and lower currents. MCB short
circuit current level is 10kA only.
ACB is ever for lower and medium voltage and high currents.
Short circuit, making and breaking currents are so high.
Both are using air for quenching medium.

what does a k rating in a transformer means?
This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.

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?

We have a couple of oil tanks at our plant. One of them does not have a lightning arrester installed. My question is it necessary to install an arrestor on every tank or will this particular one be covered by the arrestor installed on the ajdacent tank, Since all the tanks are close to each other. Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
