Issue:
What are the Instantaneous override value for the Powerpact P, R and Masterpact?

Product Line:
Circuit Breaker

Environment:
Powerpact P, R frame,  Masterpact NT, NW

The instantaneous setting can be turned OFF if the breaker has the Short Time function (5.0 or 6.0 trip unit). BUT, there is an instantaneous override function which will trip the breaker instantaneously on a high-level fault. See attachment for override values.
