Hager RCBO-AFDD ARC Fault Detection Device

The Hager RCBO-AFDD ARC Fault Detection Device is a groundbreaking electrical safety device that combines the functionality of a residual current circuit breaker (RCCB) and an arc fault detection device (AFDD) into a single, compact unit.

This advanced device offers comprehensive protection against electrical hazards, including:

  • Residual current faults: The RCCB component of the RCBO-AFDD detects and interrupts dangerous electrical currents that can flow through the ground wire, preventing electrocution and electrical fires.

  • Arc faults: The AFDD component detects and interrupts dangerous electrical arcs, which are a major cause of electrical fires. This feature provides an additional layer of protection beyond traditional circuit breakers, which are not designed to detect arc faults.
