Catalog excerpts

• A 6-mm-0 fuse, which is the of the same size as a glass tube fuse,can be used to implement a current blocking capacity of 1 OkA at 500V • Able to block off even DC # UL approved for up to rated 20A • Space-efficient (500SF/SFK) •250SF/SFK Rated voltage and blocking capacity: 250V AC-1 OkA, 250V DC (UR = 1 Oms)-1 OkA Minimum block-off current: 250V AC/DC- 4 times the rated amperage Maximum arc voltage: 500V •500SF/SFK Rated voltage and blocking capacity: 500V AC-1 OkA, 500V DC (L/R = 2ms)-l OkA Minimum block-off current: 500V AC/DC- 4 times the rated amperage Maximum arc voltage: 1OOOV UL/cUL standard approved rating Rated voltage and blocking capacity: Same as the standard rating. When applying the standard to UL standard approved items, use the fuse in the following rating. The CCC standard is an option. Enter "TC" at the end of product name when ordering (e.g. 500SF-10ULTC). Rated voltage and breaking capacity :500V AC-50kA, 500V DC (L/R=10ms)-50kA (250SF/SFK are not CCC approved.) CAUTION! • 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.

Shutdown lgt Against Working AC Voltage_Current-Limiting Characteristics Application to Direct-Current Circuit Power Loss and Temperature Characteristics •Testing Conditions for Board-Soldered-Type Fuses The power loss and the temperature characteristics are studied using an FR4 board (one-side board) and a 35-jum-thick copper foil with a copper foil width of 0.5 mm/A depending on the rated amperage (e.g. 5 mm width for a product rated at 1OA).
