MAXI Blade Fuse Littelfuse MAXI Slo-Blo (Series 299), 32V, 20 - 80A

The fuses of the Littelfuse MAXI Slo-Blo Series 299 are specifically designed to protect high-power circuits in 12- and 24-volt systems. With their time-delay characteristic (Slo-Blo®) and advanced diffusion pill technology, they provide a controlled delay during short-term overcurrent conditions—without compromising operational safety.

This makes them ideal for applications with typical inrush currents, such as those found in inverters or high-performance battery chargers.
