The TJN series 300 VAC and TJS series 600 VAC fuses are fast-acting fuses in a compact, space-saving size, making them ideal for panel boards, load centers, meter stacks, and AC drives. Available in one to 600 Amp sizes, the fuses are current limiting and are designed with no intentional time delay to open quickly on overload. Screw and box lug-type fuses blocks for Class T fuses are also available.
