You have a 40 amp breaker. It's normal for a breaker to hold until about 20% over its rating (common for fuses too). Manufacturers even publish "trip charts" which document how long it will take a fuse or breaker to trip depending on level of overload. All common fuses and breakers I've ever researched are roughly in that 20% above range, after that, time to blow all depends on the extent of the
Overload.
