EC&M Awards Littelfuse "Product of the Year" Category Winner for PGR-5330 Advanced Ground Fault and Resistor Monitoring Relay

CHICAGO--(Business Wire)--
Littelfuse, Inc. the global leader in circuit protection, today announced that
it has won Electrical Construction & Maintenance (EC&M) magazine`s "Product of
the Year" award in its category for the PGR-5330 advanced ground fault and
resistor monitoring relay.

The PGR-5330 increases safety and reliability by continuously monitoring the
facility electrical system for damaging ground faults or neutral grounding
resistor problems. These dangerous conditions directly impact the safety of
personnel or the reliability of the electrical equipment.

"The PGR-5330 ground fault and resistor monitoring relay is a critical component
in a building`s electrical system. Without it, a resistor failure can go
undetected until there is serious damage to equipment or personnel, and by then,
it`s too late," explains Tony Locker, Product Manager, Littelfuse POWR-GARD
Protection Relay Products. "The PGR-5330 provides that vital early warning that
can signal a serious problem before it happens. It also offers pulsing
capability to help the user quickly locate the problem."

The PGR-5330 is a microprocessor-based relay that filters out system noise from
modern electronics. It can connect to Ethernet, DeviceNet or Profibus® networks
and enables plant managers increase plant efficiency by safely maintaining
critical operations and avoiding damaging ground faults.

The EC&M Product of the Year competition honors exceptional contributions in the
area of new product development for the electrical industry. "Our goal is to
design smart products that improve electrical safety and productivity for our
customers. We are thrilled to be the Product of the Year winner in our
category," says Maureen Janosch, Marketing Manager of Littelfuse POWR-GARD
Electrical Business Unit.
