The PICO® 304 Series offers a range of suface mountable encapsulated fuses certified under UL 913, the standard for intrinsically safe electrical equipment, to operate in hazardous locations. Ideal for use in oil, gas, mine, chemical, and pharmaceutical 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 an intrinsically safe apparatus and associated apparatus for peak voltage not exceeding 375V.

Notes: 1) The fuse must be mounted so that creepage and clearance distances are not impaired in any way. 2) The fuse is suitable for use in intrinsically safe equipment and associated apparatus for voltage not exceeding 375V peak. 3) Maximum surface temperature rise at 170% rated current: = 52°C, and © 2017 Littelfuse, Inc.
