Littelfuse Automotive Maxi Blade Slow Blow Fuse 50A
50A time-delay Maxi blade fuse for automotive & motor control. Silver-plated terminals, 32V DC rating. Replaces fusible links.
The Littelfuse Automotive Maxi Blade Slow Blow Fuse is a premium 50-amp circuit protection component designed specifically for demanding motor-powered applications with high inrush currents, such as those found in modern automotive and motor drive control systems.
Engineered with patented diffusion pill technology, this MAXI-series fuse offers reliable time-delay (slow blow) characteristics. This allows it to withstand the temporary surge of current when a motor starts up, without blowing unnecessarily, while still providing robust protection against sustained overloads and short circuits.
Its construction features a plastic body with silver-plated terminals, which ensures excellent electrical conductivity and low heat dissipation. This design enhances both performance and safety in high-current environments. A key modern application is the protection of the vehicle's main wiring harness, where it effectively replaces traditional fusible links or fusible wire, offering more precise and reliable protection.
With a low cold resistance of 0.0011Ω and a high interrupting rating of 1000A at 32V DC, it provides a critical safety margin, capable of safely breaking severe fault currents. The distinctive red body allows for easy visual identification of its 50-amp rating within the fuse box.
Ideal for automotive electrical systems, motor controls, and any circuit requiring durable protection against overloads, this fuse combines advanced Littelfuse technology with robust construction for dependable, long-term performance.
