Arc-Flash Microprocessor-Based Protection Relay - PGR-8800 Series
Littelfuse arc-flash relay is microprocessor-based to detect an impending arc-flash in less than 1 ms
The PGR-8800 series from Littelfuse is a microprocessor-based relay that limits arc-fault damage by detecting the light from an arc flash and rapidly tripping. 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 and a USB port is used for configuration and access to event logs and graphs.
Features
- Lowers the PPE category or incident energy of the equipment
- Protects against equipment damage and potential injury to personnel
- Easily installed without changes to the existing layout
- Flexible sensor configuration for any application (up to 24 available)
- No additional software is required
