Special Application Fuses PICO® 259-UL913 Series Intrinsically Safe Fuse for Hazardous Locations PICO® 259-UL913 Series Intrinsically Safe Fuse Baseefa Description The 259-UL913 Series offers a range of encapsulated fuses approved under the UL 913 standard for Intrinsically Safe Electrical Equipment to operate in hazardous locations. Ideal for use in the oil, gas, mine, chemical, and pharmaceutical industries, the 259-UL913 fuse was designed to limit the energy and temperature generated during its operation. In addition to UL913, these fuses meet ATEx and IECEx requirements. The fuse design and its encapsulant are suitable for use in intrinsically safe appartatus for voltage not exceeding 125V rms (190V peak).
