The PGR-8800 Arc-Flash Relay protects personnel, equipment, and reputation by rapidly detecting developing arc-flash incidents and tripping the circuit before significant damage occurs. The PGR-8800 can detect an arc flash in less than 1 ms, making it one of the fastest arc-flash relays on the market. 
It detects both current and light to minimize nuisance trips and provides overcurrent protection. With 24 photoelectric or fiber-optic sensors, the PGR-8800 offers complete coverage for your application—no matter how challenging the space.
