Special Application Fuses

PICO^®304 Series Fuses > 277V UL913 Intrinsically Safe Fuse

PICO^®304 Series – 277V UL913 Intrinsically Safe Fuse

RoHS

Description

The PICO^®304 Series offers a range of suface mountable

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 industries, the PICO 304 Series surface

mountable 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 are not 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 = 88°C, 250mA = 52°C, 500mA = 52°C, and 750mA = 45°C.

Speciﬁcations are subject to change without notice.
