Discuss Time Current Curves of Various MCBs and MCCBs in the UK Electrical Forum area at ElectriciansForums.net
They will be "similar" in the sense the time constants, etc, are engineered to protect typical PVC/XLPE style cable insulation, but not identical. However, I would expect them to be no more than a few times different in terms of time for a given thermal overload ratio.Nice, thank you for this!
Do larger MCBs and MCCBs have similar curves?
4.5 times for 10 seconds, 6 times for 5 seconds and 10-20x for 1 second.
