Note: All fuses should be rated at 125 percent of connected load or the next standard fuse size above 125 percent. Due to special cases such a cooler ambient or lower amperage loads, the connected load should be the determining factor. The semiconductor fuse 1²t rating must not exceed the SCR 1²t rating. Semiconductor fuses are classified as supplemental protection for semiconductor. They are not approved for branch circuit protection.
