MOMENTARY OVERLOAD

1ꢀ Momentary overload (> 2 s):

See example in table below. In all cases, it should be understood that:

- the 12 Pn overload applies only to ohmic values 0.1.

- the overload voltage shall not be higher than that used for the dielectric strength test (see Standard Electrical Specifications).

2ꢀ Short time overload (< 2 s):

For times shorter than 2 seconds, higher overloads can be sustained in some cases. Consult VISHAY SFERNICE.
