•Three types are available for choice according to the installation method. • Compact and light-weight, also excellent for prompt cut-off action when blocking off. • Most suitable for small inverters, servos, UPSs, power supplies, etc. • Compliant to all types of standards. •A 10-mm-0 fuse is compliant to the 50 A class. •Rating 5 - 60 A Rated voltage and blocking capacity: 660V AC-1 OkA, 660V DC (L/R = 1 Oms)-1 OkA Minimum block-off current: 660V AC - 6 times the rated amperage 660V DC - 20 times the rated amperage 570V DC - 8 times the rated amperage Maximum arc voltage: 1320V 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. • Fusing indication function is not provided. UL/cUL standard approved rating When applying the standard to UL standard approved items, use the fuse in the following rating. •Rating 5 - 30 A Rated voltage and blocking capacity: Same as the standard rating •Rating 35 - 60 A Rated voltage and blocking capacity: 660V AC-lOkA, 570V DC (L/R =2ms)-l OkA (660KH/KHK are not cUL approved.) CCC standard approved rating When applying the standard to CCC 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. 660KH-30ULTC). Rated voltage and blocking capacity: 660V AC-lOkA, 450V DC (L/R = 1 Oms)-l OkA Standard Approved
