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
  • Encapsulated and sealed (1mm minimum)
  • High breaking capacity of 1500A at 277V AC/DC
  • Current rating options ranging from 0.050A to 0.750A
  • Global hazardous locations certifications


  • Suitable for pick-and-place PCB assembly
  • Eliminates the need for encapsulation (potting) or coating, which saves assembly time and money, reducing total end-product cost
  • Ideal for interfaces between intrinsically safe and non-intrinsically safe circuits
  • Enables reduction of power ratings and current-carrying capacity of downstream components, wiring, and circuit board traces
  • Speeds up the certification process for end-products


  • Testing, measuring or processing electronic and electrical equipment
  • Motor controllers
  • Communication handsets/two-way radio and associated accessories
  • Process control and automation
  • Sensors
  • Lighting
  • Flow/gas meters
