Circuit Breaker Ratings Explained by waqas_a_shaikh4348 is a document available to read on EtoBox.
The rating of a circuit breaker includes its rated short circuit breaking current, rated short circuit making current, rated operating sequence, and rated short time current. The short circuit breaking current is the maximum fault current the breaker can withstand before opening without damage. The short circuit making current is higher, typically 2.5 times the breaking current, to withstand fault currents when closing on a fault. The rated operating sequence specifies the timing of open-close operations. T
