PERCENTAGE OF RATED CURRENT VS TRIP TIME IN SECONDS
The table above provides a comparison of inrush pulse
tolerance for each of the 50/60Hz delays. Pulse tolerance is
defined as a single pulse of half sine wave peak current
amplitude of 8 milliseconds duration that will not trip the
circuit breaker. Consult Sensata Technologies for further
assistance.
