PGR-8800The Littelfuse PGR-8800 arc-flash relay protects personnel and equipment by rapidly detecting developing arc-flash incidents and tripping the circuit before significant damage occurs. This relay can detect an arc flash in less than 1 msec, and it detects both current and light to minimize nuisance trips and to provide overcurrent protection. The compact, stand-alone unit features up to 24 light sensors, including optional fiber-optic cable sensors that can protect difficult-to-reach compartments. The relay offers adjustable light level and wide-angle detection, built-in LED to indicate local sensor health or trip state, and application tool s to help determine sensor placement and maintenance schedules.
