Question: LV Switchgear
Answer: 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 you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart? |

For Short circuit fault, SFU is popular, but now days, In Indian market due to reduced rate MCCB with Earth leakage are mostly used as these are automatic and faster. |
