Arc-Flash Relay Arc-Flash Detection - Littelfuse

Arc-flash events are dangerous and potentially fatal to personnel. Arcing and arc-flashes occur when electricity flows across what is normally an insulating medium, producing intense, luminous discharges of electrical energy.

Arc-Flash Solutions Schweitzer Engineering Laboratories

SEL arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, which reduces hazardous arc-flash incident energy. SEL-751 Feeder Protection Relays and SEL-849 Motor Management Relays combine light-sensing technology with fast overcurrent protection to provide high-speed arc-flash detection (AFD).


Arc Flash relay in combination with a circuit breaker will lower the incident energy or Arc Flash hazards. This results in an increase in worker safety, less fault damage, and improved uptime. Since the arc-flash hazard has decreased, the associated PPE may also be lowered. The exact amount will depend on user setpoints, so it must be

Each sensor can detect both light and sound from an arc flash event. The arc flash can be detected as quickly as 1 ms. Self-supervision


Do the Littelfuse Arc-Flash Relays relay detect ultra-violet light? The typical spectrum of light from an arc-flash is spread across the visible spectrum and so this is what the PGR-8800, AF0500 and AF0100 relays are detecting. Ultraviolet light is mostly used to detect corona which can be present before an arc flash but is
