Overview

The Littelfuse PAL250 (SKU: PAL250) is a robust 50-ampere, 32-volt DC/AC auto link fuse engineered for critical high-current circuit protection. As part of Littelfuse’s trusted PAL™ series, this fuse delivers reliable overcurrent protection with secure bolt-on terminals, ensuring vibration-resistant connections essential for heavy-duty applications. The 13/16 BNT BOX size ensures compatibility with standard fuse blocks and panels, making it a direct replacement for OEM and aftermarket systems. Key specifications include a 50A current rating and a 32V voltage rating. The PAL™ series fuses are known for their Slo-Blo® time-delay feature, which effectively prevents nuisance blowing during temporary overloads. The bolt-on terminal design provides a firm mechanical and electrical connection, crucial for high-amperage circuits where intermittent connections can lead to arcing or system failures. Constructed from high-quality materials, the PAL250 is built to withstand harsh operating conditions, including temperature extremes and electrical stress, ensuring long-term reliability. This fuse is ideal for a range of demanding applications such as automotive electrical systems in trucks, buses, and heavy equipment, industrial machinery, RV and marine systems, and any environment requiring dependable high-amperage circuit protection. The color-coded design (red for 50A) simplifies identification and inventory management. Backed by Littelfuse’s reputation for innovation and quality, the PAL250 offers a cost-effective solution for safeguarding critical electrical systems from damaging overcurrents and short circuits. The catalog indicates PAL™ fuses are available in current ratings up to 120 amperes with either female or bolt-on terminals.
