- Increase of ambient temperature over 20¡ãC will cause
current passing the resettable fuse dropping swiftly.
- When ambient temperature being at 20¡ãC, 100 % of current
on the line will pass through the resettable fuse, but if
there are still so much current as over doubling the rated
value produced, the resettable fuse will operate.
- The higher the ambient temperature, the larger the passing
current and the shorter the operating time. The reduction
rate of ambient temperature and current value is shown as
following table:
