waross, could you please share a link which explain your comment in detail?

what is the difference between single voltage rated MCB and dual voltage rated MCB?

what is the practical meaning of Ics and Icu?

can anyone explain meaning of these Icu and Ics values? what is the meaning of that Ics=100% of Icu? how Icu and Ics differs for different voltages? why Icu and Ics values defined for single phase voltages as well even though MCCB is a multi pole device which will always get voltage over 400V?

what is the difference between type F and IEC connector shown as below? http://img.weiku.com/a/016/980/20dB_DVB_avtive_car_TV_antenna_with_VHF_UHF_RG_174_Coaxial_Cable_CL_DVB_030A__4751_1.jpg

what is the cable type that i use for connecting antenna and a Terrestrial television or broadcast television(analog)? there are 3C-2V, 5C-2V, RG 59 and RG 6 cable types. what type of cable should i use?

can someone clarify why short circuit current rating getting decreased like this?

how can i calculate and get the fault current value as 7kA for a 25kVA transformer?

could u pls give me more information for the reason why we need higher kA rated MCB for industrial? is there any technical reference guide from that i can get a more clearer idea abt this?

how to choose a MCB from 3kA, 4.5kA MCB, 6kA MCB and 10kA MCB for domestic application? i have seen 10kA MCB are used for industrial applications. but why industrial applications need 10kA MCB instead of 3kA, 4.5kA MCB, 6kA MCB what is the thumb rule of selecting short circuit capacity of a MCB.

should a 10kA MCB be riveted with Al rivets or Cu rivets?

what is the best rivet type to be used for 10kA(short circuit capacity) MCB rivets? can Al rivets withstand higher kA rating or is it Cu rivets?

but why only line terminals are burnt? not load terminals or any other cable burnt. can heat from a overload current melt the tightening screws also?

hello, can anyone tell me most probable reason for this kind of RCCB(4P, 400V, 63A, 100mA, 3kA) burn out. there was isolator in the system before this RCCB. can this happen due to a lightening strike? then why isolator didnt burn out first?

conforming that the panel is ok for EU LV and EMC regulations?
