Time vs. Current Trip Curves For W6 Series and W9 Series

Note:

For instantaneous curves for all voltages refer to Curve 0 Instantaneous under the AC 50/60 Hz. heading.

Pulse tolerance is defined as a single pulse of a half sine

wave (1/2 cycle or 8 milliseconds) that will not trip the

breaker. An inertia wheel for increased pulse tolerance is

available by specifying “P” after the time delay curve

number in the ordering information. The table at right lists

pulse tolerance values of standard and inertia delay models.

To determine pulse tolerance multiply breaker rating by value in table. For

example, a 2A breaker with time delay curve 3 has a standard pulse tolerance

of 12A (2A x 6). The same breaker with an inertia delay has a pulse tolerance

of 36A (2A x 18).
