AFDD Fault Arc Circuit Breaker

 

 

This device provides proactive fire prevention by detecting dangerous arc faults—the leading cause of electrical fires—before they escalate. It combines arc fault detection with reliable circuit breaking, effectively preventing ignition from overheated wires, loose connections, or damaged cables. Its anti-misoperation design ensures stable performance, avoiding false trips caused by normal electrical system fluctuations, thus guaranteeing continuous and safe power supply.

 

 

Designed for single-phase systems (AC230V), it offers rated currents from 6A to 63A and a short-circuit breaking capacity of 4.5kA. It integrates leakage protection (default 30mA) alongside arc fault detection, with a compact form factor supporting standard 35mm DIN-rail installation. Key specifications include low power consumption (<1W), a dielectric strength of 2000V, and IP20 ingress protection, ensuring durability and safety in diverse environments. It has a mechanical lifespan of 10,000 operations and an electrical lifespan of 2,000 cycles for long-term reliability.

 

 

Widely used in residential electrical systems, commercial buildings, and retrofitting of old electrical systems, it is especially critical for high-risk public spaces such as hospitals, schools, and commercial kitchens, providing essential fire safety protection for both new and existing electrical infrastructures.
