MOMENTARY OVERLOAD
1. Momentary overload (> 2 s):
See example in table below. In all cases, it should be understood that:
- The 12 P
- The overload voltage shall not be higher than that used for the dielectric strength test (see Standard Electrical Specifications).
2. Short time overload (< 2 s):
For times shorter than 2 s, higher overloads can be sustained in some cases. Consult Vishay Sfernice.
