EARU AFDD-63 Arc Fault Protective Device 2P RCBO Circuit Breaker

EARU AFDD-63 Arc Fault Protection and Specifications

The EARU AFDD-63 detects dangerous arc faults within milliseconds using proprietary sensing technology, interrupting circuits before fires ignite in walls or junction boxes. Dual-pole configuration protects both phase conductors simultaneously, addressing the leading cause of residential electrical fires that standard breakers miss. Earth leakage detection responds at 30 mA sensitivity, catching ground faults that pose electrocution hazards to users and equipment alike. Short circuit protection operates at rated current thresholds, preventing thermal overload in branch circuits tied to motors, heaters, and high-draw appliances. The compact DIN-rail form factor installs directly into standard distribution boards without modification, saving time during new construction or retrofit projects.
