Does all the output contacts (N/O as well as N/C) of a Numerical relay operate when relay receives a binary input/inputs or contacts are designated to specific logic input/inputs and only these contacts operate?1241
comparision between ACB and VCB
do anyone out there know where to find a compleete list on acronyms/abbreviations used in offshore electric engineering. MCB - Micro Circuit Breaker, MCCB-Mouldes Case Circuit Breaker, ELCB-Earth Lekage Circuit Breaker, ELMCB- etc.....
why we have to particulary use ACB for below ratings,even available of MCB,MCCB with that range ?
