Electrical Speciﬁcations by Items

Schedule of limitations:

1) The fuse must be so mounted 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

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).
