AutomationDirect's TJN series 300V ac and TJS series 600V ac fuses are extremely
fast-acting fuses in a compact, space-saving size, making them useful for use
as the main fuse protection for panel boards, load centers, meter stacks and AC
drives. Available in one to 600A sizes, the fuses are current limiting and are designed with no intentional time delay to
open quickly on overload. Class T fuse prices start at $6.50 for a single fuse,
or $65 for a 10-pack. Screw and box lug-type fuses blocks for Class T fuses
have also been added, starting at $8.50.
