Overview

The Littelfuse AGX3 (SKU: AGX3) is a precision 8AG glass fuse designed for reliable overcurrent protection in automotive and industrial electrical systems. This fuse features a 3 Amp current rating and a 125 Volt voltage rating, making it suitable for circuits operating at or below this voltage. The 8AG size, measuring 1/4" diameter by 1" length, ensures compatibility with standard fuse holders and electrical configurations. Constructed from durable glass, the AGX3 offers excellent resistance to environmental factors and allows for easy visual inspection of the fuse element to quickly identify blown fuses. Originally, the 'AG' prefix stood for 'all glass,' a designation common in the automotive industry for glass fuses like the AGC and AGW variants. While widely used in automotive applications, the AGX3's robust construction and precise protection capabilities make it an excellent choice for industrial uses, including control panels, power supplies, and specialized equipment requiring dependable circuit interruption. Manufactured by Littelfuse, a recognized leader in circuit protection technology, the AGX3 meets stringent industry standards for electrical safety and system integrity. Key specifications include: Current Rating: 3A, Voltage Rating: 125V, Size: 8AG (1/4" x 1"), Material: Glass, Packaging: Boxed (5-piece). UNSPSC code: 39121622. Country of Origin: US.
