Well spotted. Suggests no more than about 500w worth of LED fittings on a 10A B type, or more like 3 times than on a C type.
No mention of the UK standard of 6A in either B or C type sadly.
Also of interest is the quoted response of typical MCBs to very short duration surges, down to about 50usec. This is not something in the normal datasheets, but is potentialy very useful.
This is not the fault breaking time of course, just the time that will get the release mechanism beyond the point of no return (de-latched)
Interestingly for the last order of magnitude of time we move almost exactly an order of magnitude in current too. Part of me wonders if many intermediate points were measured, or if this really is a sharp change in power law and then a straight line between 2 test settings.
