Littelfuse PGR-8800 - Improve Electrical Safety & Reliability With Instant Arc Flash Detection

​​T&D are distributors for the Littelfuse range of Powr-Gard Fuses, blocks, holders, relays, controls and MOVs.

Littelfuse products help protect low and medium voltage electrical equipment used in construction, general industrial, oil and gas, solar, mining and OEM applications offering a broad and reliable selection of fuses, fuse blocks, protection relays and generator controls to improve safety and reduce downtime.

Today, T&D present a guest blog from Littelfuse's Area Sales Manager Morten Mortensen who explains the dangers of arc flash events.Littelfuse

According to OSHA, industrial Arc-Flash events cause about 80% of electrically related accidents and fatalities among qualified electrical workers. Even if personnel injuries are avoided, arc flash can destroy equipment, resulting in costly replacement and downtime.

The PGR-8800 from Littelfuse is a microprocessor-based arc protection relay that limits arc-flash damage by using light sensors to rapidly detect the arc and then trip a circuit breaker.

The Littelfuse PGR-8800 offers extremely fast arc-flash detection and reacts in less than 1 ms and the point and fibre sensors can be used in combination to suit different applications.

Phase current-transformer inputs are provided for current-supervised arc-flash protection and can also be used for definite-time overcurrent protection. Sensors, inputs, and trip-coil voltage are monitored to ensure fail-safe operation. A secondary solid-state circuit provides a redundant trip path.

Littelfuse PGR-8800 Arc-Flash Relay and sensors are easily retrofitted into existing switchgear or pre-installed in new equipment with little or no configuration.

Even elaborate systems only take minutes to configure using the relay’s built-in USB interface software. The compact size of the Littelfuse PGR-8800 arc flash relay allows installation in any switchgear and power converter cubicle, transformer compartment, or motor control centre bucket.
