Clarification on Trip/Non-Trip Bands as per IEC - Product Specific
03/07/2017 4:45 AM
Why products falling under IEC60947-2 (ACB/MCCB) have Trip/Non-Trip as 1.05/1.30 times of In while products falling under IEC60898 have the same as 1.13/1.45 (MCBs) time of In? In practical usage, is it not that as MCBs being handled by unskilled personnel, it must have lower trip/non-trip compared to ACBs/MCCBs? Thanks in Advance.
