Littelfuse Arc-Flash Relay Wins Plant Engineering Product of the Year Award

Littelfuse, Inc., the global leader in circuit protection, announces that its AF0500 Arc-Flash Relay was named a Gold winner in the Electrical Safety category for Plant Engineering‘s 2015 Product of the Year Awards. The prestigious award recognizes outstanding achievements in innovative products for manufacturing.

At an awards ceremony in Chicago, Debra Jayson, Marketing Manager, Littelfuse accepted the award on behalf of the company. “We are grateful to the readers of Plant Engineering magazine who voted for the AF0500 arc flash relay,” she said. “They responded to its plug-and-play installation, and Heartbeat™ indication, which lets workers see if the protection is working as soon as they open the door of the electrical cabinet.”

Jayson is proud of the Littelfuse leadership in arc flash detection that makes it easier than ever to keep workers safe and comply with OHSA and NEC safety standards. Arc flash events are characterized by intense heat and explosive force and have killed and injured workers through burns, blast, and shrapnel. The AF0500 Arc-Flash Relay protects workers and equipment by using light sensors to detect an emerging arc and send a trip signal to the circuit breaker in less than a millisecond. The reduced time to trip lowers the incident energy and helps protect plant maintenance and electrical workers from dangerous electrical arc flash.

Plug-and-play installation means that a PC is not required for set up making it ideal for retrofit applications. Each input accepts either point- or fiber-optic sensors, simplifying set up and avoiding cost. What’s more one AF0500 relay can be set up to trip different zones, eliminating the need to buy separate relays for each zone.
