250SFK/500SFK
CCC standard approved rating
When applying the standard to UL standard approved items, use the fuse in the following rating
| Rated voltage and breaking capacity | 500V AC–50kA, 500V DC (L/R = 10ms)–50kA |
|---|
(250SF/SFK are not CCC approved.)
※Read “FOR SAFE USE” and “PROTECT FUSE USER’S GUIDE” at the back of this catalog before use.
※A small fuse may generate a relatively large amount of heat, so a fuse with sufficient capacity is recommended for long, continuous use.
