Current limiting definitions
SH201 Miniature Circuit Breaker is UL tested and certified as current limiting protective device, and provides a high level of circuit protection than a typical zero point external breaker.
UL breaker current limiting
UL defines breaker current limiatation as a breaker that interrupts and isolates a fault in less than 1/2 of an AC cycle, 1/2 a cycle is completed in 8.3 miliseconds.
IEC 60947-2 current limiting circuit breaker
A circuit breaker with sufficiently short trip time to prevent short circuit from reaching the peak value which would other be reached.
