Class J Fuses
Class J fuses provide overcurrent protection by quickly interrupting excessive electrical flow caused by overloads and short circuits, minimizing the risk of equipment damage and electrical fires. These fuses feature time-delay capabilities to handle inrush currents, making them ideal for protecting motors and transformers. Class J fuses are single-use devices that must be replaced after operation. Discover our selection of Class J fuses for industrial and commercial applications at LiveWire Electrical Supply.
