Effect of Ambient Temperature
1. Increase of ambient temperature over 20¡ãC will cause current passing the resettable fuse dropping swiftly.
2. When ambient temperature being at 20¡ãC, 100 percent of current on the line will pass through the resettable fuse, but if there being such much current as over doubling the rated value produced, the resettable fuse will operate.
3. 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:
