Special Application Fuses

PICO^®259-UL913 Series Intrinsically Safe Fuse for Hazardous Locations

PICO^®259-UL913 Series Intrinsically Safe Fuse

RoHS

Description

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).

Schedule of limitations:

Additional Information

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.
