Special Application Fuses

Intrinsically Safe > Radial Leaded > PICO^®305 Series Fuse

PICO^®305 Series - 277V Intrinsically Safe Fuse

RoHS

Description

The PICO^®305 Series Fuse offers a range of encapsulated

fuses certiﬁed under UL 913 , the standard for intrinsically safe

electrical equipment, to operate in hazardous locations. Ideal

for use in oil, gas, mine, chemical, and pharmaceutical process

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 peak

voltage not exceeding 375V.

Notes:

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.

Speciﬁcations are subject to change without notice.
