PGR-8800 - ARC Flash Detection Relay

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.

The PGR-8800 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.

Features & Benefits
  • Arc-Flash trip time - <1 ms Limits arc-flash damage and risk of injury
  • Multiple sensors (up to 24) - Single module can monitor 6 sensors. Up to 4 PGR-8800 units can be linked into one system
  • Fail-safe system - Continuous monitoring of optical sensors and inputs ensures protection
  • Redundant trip circuit - Solid-state backup arc-detection circuit adds a second layer of safety
  • Adjustable light sensitivity - Allows for operation in bright environments and maximum sensitivity in dark environments
  • LED indication (on unit and each sensor) - 18 LEDs provide at-a glance status for module and I/O state
  • Current detection - Phase-CT inputs provide overcurrent protection and prevent nuisance trips
  • Optical detection - Point and fiber-optic sensors provide wide detection area with sensor health trip indication
  • Digital inputs (6)- Two each: remote trip, inhibit, and reset inputs
  • Service mode - Allows for system test without tripping
  • Trip coil contact - Solid-state 24-600 Vdc/24-440 Vac IGBT
  • Indication contacts - Form C and status outputs
  • USB interface - Data logging and configuration software uses a USB interface with no drivers or software installation
  • Built-in sensor - Can be used in single-sensor systems, as a seventh sensor, and for calibration
  • Universal power - Supply/Battery backup - 100-230 Vac, 12-60 Vdc, or 100-250 Vdc supply accepted. Ability to charge and run off an external, user-supplied 24 Vdc battery.
  • Data logging - On-board event recorder helps with system diagnostics
