AutomationDirect has added two series of Class T fuses to their line of circuit protection products. The TJN series 300 VAC and TJS series 600 VAC fuses are extremely fast-acting fuses in a compact, space-saving size, making them ideal for use as the main fuse protection 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.
