Extension module REA 103

Arc fault mitigation devices

The REA 103 extension module operates as additional light-detecting module in the REA arc fault protection system.

Scope

  • Extend the arc detection zone of the main REA101 module with additional sensors

Product benefits

  • Extends the arc flash detection area by two fiber sensors in loop or radial arrangement
  • Detects light and provides the operator with information about the location of the fault with LED indicators

 Product features

  • Two arc light detection sensor inputs
  • Separate Light-detected signal contact outputs for both sensors, latched if the main REA 101 module simultaneously has detected overcurrent and tripped
  • Self-supervision monitors the operating voltages and integrity of the sensor fiber loops
