Overview

The Littelfuse MEGA® Fuse Block (SKU: 02980900Z) is a high-current protection solution designed for demanding electrical applications requiring up to 500A of current handling. This fuse block is engineered for use with Littelfuse MEGA® fuses (80-500A), featuring patented Diffusion Pill Technology for superior time-delay characteristics that prevent nuisance blowing during temporary overloads. The block includes a protective cover for enhanced safety and environmental shielding, making it ideal for harsh operating conditions. Key features include side-mounted interconnecting pins for secure modular configurations of multiple blocks, simplifying complex electrical system management. Installation is facilitated by M8 threaded studs, hex nuts, and lockwashers, ensuring a stable and vibration-resistant mounting. The fuse block is rated for 32V AC/DC operation and is suitable for battery and alternator connections, as well as heavy-gauge cables requiring ultra-high current protection. Common applications include automotive, marine, industrial, and heavy equipment sectors where reliable circuit protection is critical. The MEGA® Fuse Block is part of Littelfuse’s MEGA® series, known for its robust construction and advanced protection capabilities. The block does not include the fuse itself, allowing users to select the appropriate MEGA® fuse (e.g., 0MEG500.L for 500A) based on their specific requirements. The UNSPSC code 39121622 classifies this product under electrical circuit protection components.
