Deschamp installed the Littelfuse PGR-8800 Arc-Flash Relay in the controls section of the cabinet, with two light sensors mounted in each of the three power compartments. The trip output of the relay was connected to the shunt trip input of the main breaker. Trial by Fire. The timing of this installation was incredibly fortunate.

The PGR-8800 continuously monitors its internal circuitry as well as the connected optical sensors. Any system faults, including a sensor-cable faul t, are indicated by a flashing LED and can be logged. A redundant trip circuit ensures that the PGR-8800 will trip on an arc flash even if a primary trip-circuit component fails.

PGR-8800 - ARC Flash Detection Relay. Arc flash is a growing source of concern for manufacturers and other employers, and increasingly companies are being cited for arc flash violations.
