Electrical Specifications by Items
Schedule of limitations:
1) The fuse must be mounted in such a way that creepage and clearance distances aren’t
impaired in any way.
2) The fuse is suitable for use in intrinsically safe equipment for voltages not exceeding
190V peak.
3) Maximum surface temperature rise at 170% rated current: ≤750mA=40ºC, 1A=55ºC,
3A=118ºC and 5A=135ºC.
The 259-UL913 Series offers a range of encapsulated fuses
certified under the UL 913, the standard for intrinsically safe
electrical equipment, to operate in hazardous locations. Ideal for
use in the oil, gas, mine, chemical process, 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 and associated apparatus for voltage
not exceeding 125V rms (190V peak).
