Description
The PICO 305-Series fuse offer a range of encapsulated fuses
approved under UL 913 standard for Intrinsically Safe Electrical
Equipment to operate in hazardous locations. Ideal for use in
oil, gas, mine, chemical, and pharmaceutical industries, the
PICO 305-Series 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 voltage not exceeding
277V.

1) The fuse must be mounted so that creepage and clearance distances aren’t 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 200mA=80°C, 250mA = 84°C, 500mA = 56°C, and 750mA = 84°C.
