Product Guide
Arc faults are common faults in power and industrial power systems. Insulation damage, operational errors, or aging equipment can cause arc faults.The traditional current protection and ground fault protection cannot reduce the hazard of arc fault due to the long detection period and slow operation time.The REA 100 Arc Protection System is an electrical arc protection relay developed specifically to detect electrical arc faults and quickly shut down faulty power supplies.In the event of an arc fault in the system, the arc of the protected area is detected by the sensing medium to quickly locate the fault and remove the faulty power supply, thereby achieving:
— Protect personal safety
— Reduce fault loss
— Easy to install and use
Two ways to detect arc light, wrap-around fiber or probe fiber, to meet the needs of different equipment and environment;
ABB's patented winding optical fiber detects the arc fault and ensures no dead zone detection;
Protect the high-speed trip outlet, the shortest action time < 2.5 ms, continuous self-test, test the fiber body and probe to ensure the system is reliable.
