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
