Issue:
The ACSC100 manual lists an In-Rush current of 56amps for 200ms.  How does this not trip the 20amp breaker?
Product line:
ACSC100
Environment:
InRow Cooling
Cause:
 
Resolution:
The reason that the circuit breaker does not trip is expressed in the time/current curve that are unique properties of circuit breakers or fuses. For example a typical Square ""D"" ""NQ"" breaker rated at 20 amps might trip after 300 seconds of a 20 amp load, but will pass considerably more than 56 amps at 200ms of time.
