Overview

The Littelfuse 359003 Screw Terminal Fuse Block (SKU: 359003) is a precision-engineered fuse block designed for reliable circuit protection in industrial and commercial electrical systems. This model is rated for 3 amperes, with flexible current handling capabilities of up to 15 amperes when equipped with spring brass clips and up to 30 amperes when fitted with beryllium copper clips. The screw terminal connection ensures secure, stable electrical terminations with minimal risk of loosening under vibration or thermal cycling, making it ideal for high-reliability applications. Key specifications include a current rating of 3A (base), expandable to 15A (spring brass clips) or 30A (beryllium copper clips). The connection type is screw terminal, providing a robust and field-serviceable interface for conductors. The fuse block is constructed from durable brass or beryllium copper materials, selected for their high conductivity, corrosion resistance, and long-term mechanical integrity. This design supports both low-current signal protection and higher-current power distribution scenarios, depending on clip selection. The fuse block’s design facilitates straightforward installation and maintenance, reducing operational downtime and simplifying field servicing. It is part of Littelfuse’s screw terminal fuse block series, with variations available for 2A, 4A, 6A, and 9A ratings, all sharing the common specification of supporting up to 15A with brass clips and 30A with beryllium copper clips. This product is categorized under UNSPSC code 39121623, aligning with electrical fuse and protector manufacturing standards.
