Rating Rated voltage and breaking capacity 500V AC-10kA, 400V DC t.c. 3mS CAUTION When you are using a fuse in direct circuit for reasons other than as a short circuit protector, reignition of arc may occur if the interrupting current is less than 4 times larger than the fuse rated current. In this case, the fuse should be used in conjunction with other protectors. The maximum arc voltage when interrupting is about twice as much as the circuit voltage. UL Standard Approved Rating Rated voltage and breaking capacity 250V AC-10kA, 250V DC (L/R = 10ms)-10kA
