LV Switchgear
Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? which one is popular in Indian Market and why? 2) Define SCPD. What is type2 co-odination? 3) Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4) If the HP rating is known then can...

2) SCPD - Short Ckt. Protection Device.eg - SFU.Type 2 coordination says that there should be no danger to personnel as well as no damage to the controller for downstream faults.Light contact welding ...

During short ckt. faults, the most reliable switchgear is SFU. It is fastest to operate and takes only few miliseconds. The operator just has to replace the fuse.MCCB is good for overload protection.
