Business Wire

CHICAGO -- March 5, 2013

Littelfuse, Inc., the global leader in circuit protection, has introduced the
PICO® 259-UL913 Series Intrinsically Safe Fuse, the first and only Fuse to be
certified under the latest revision of the UL913 Safety Standard for
Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II,
and III, Division 1, Hazardous (Classified) Locations. The PICO 259-UL913
Series is a range of encapsulated, hermetically sealed fuses that are ideal
for 125V applications in the oil, gas, mining, chemical, pharmaceutical, and
food/beverage processing industries.

The use of devices that are certified to be Intrinsically Safe (IS) is a
requirement of operating electronic equipment in potentially explosive areas.
The new PICO 259-UL913 Series Fuse is suitable for use in testing, measuring
or processing electronic and electrical equipment, motor controllers,
lighting, communication handsets, flow meters, process control and automation,
sensors and other intrinsically safe apparatus designed to operate in these
hazardous locations. The PICO 259-UL913 Series Fuse and its encapsulant
prevent heat and sparks from being exposed to the hazardous gases or dust in
the environment. The Fuse is suitable for use in intrinsically safe apparatus
for voltages not exceeding 125Vrms (190V peak). In addition to the
Underwriters Laboratories, Inc standard, these fuses meet ATEx, IECEx, and
Baseefa requirements.

“In the past, apparatus manufacturers have traditionally been forced to send
fuses to a third-party supplier or create their own secondary process to
encapsulate the entire fuse to meet the requirements of the UL 913 standard,”
said Juan Morales, Product Director of the Series 259-UL913 Fuse product line.
“Now, the PICO 259-UL913 Fuse can help reduce total product cost. It is ideal
for applications in a wide range of industries because it is designed to
operate within environments where there is danger of gas or dust explosion
from faulty circuits.”

The PICO 259-UL913 Series Intrinsically Safe Fuse offers these key features
and benefits:


  *Hermetically sealed, encapsulated design
  *Well suited for 125V applications
  *Current rating options from 62mA to 5A
  *Designed for operation in a range of hazardous environments
  *RoHS compliant


  *The fuse encapsulation prevents heat and sparks from being exposed to the
    hazardous gases or dust in the environment
  *Eliminates the need for an additional potting, epoxy, or encapsulation
    process for the fuse, thereby reducing total product cost
  *Increases overall safety of the apparatus, which enhances protection of
    human life in hazardous operating environments


Littelfuse PICO 259-UL913 Series Intrinsically Safe Fuses are packaged in bulk
in quantities of 10 or 1,000 pieces. Samples are available now for bulk
orders; sample requests can be placed through authorized Littelfuse
distributors worldwide. For a listing of Littelfuse distributors, please visit
