Overview
Relay, Microprocessor-Based, Limits ArcFault Damage by Detecting the Light from an Arc Flash and Rapidly Tripping.
The PGR-8800 is a UL and cUL Listed Arc-Flash Relay that reliably detects developing Arc-Flash incidents without nuisance tripping by looking for a combination of excess light and current. Phase-current-transformer inputs are provided for current-constrained arc-flash protection and, when so equipped, a programmable definite-time overcurrent function can be enabled. An optical sensor on the PGR-8800 and adjustable trip level reduce the chance of nuisance tripping by setting a threshold for ambient light. Sensors, inputs, and connections are monitored to ensure fail-safe operation. A secondary solid-state trip circuit provides a redundant trip path. A USB port is used for configuration and access event logs and graphs.
