0304.500 - PICO® 304 Series

Roll Over to Zoom
The PICO® 304 series offers a range of surface mountable encapsulated fuses certified under UL 913, the standard for intrinsically safe electrical equipment, to operate in hazardous locations. This fuse is ideal for use in oil, gas, mining, chemical, pharmaceutical, food and beverage, and other process industries. The PICO® 304 series surface mountable fuse was designed to limit the energy and temperature generated during its operation. The fuse design and its encapsulant are suitable for use in intrinsically safe equipment and associated apparatus for peak voltage not exceeding 375V. In addition to UL 913, these fuses meet ATEX and IECEx requirements.


  • Surface mount device
