Arc Fault Detection Device (AFDD)

AFDD

AFDD is a next-generation electrical protection device that detects arc faults in real time and automatically disconnects circuits to prevent fire hazards. It combines arc detection, overload protection, and short-circuit protection in one compact solution, making it ideal for modern electrical safety systems.

The AFDD Series is an advanced arc fault detection solution designed to prevent electrical fires at the source. By continuously analyzing current waveform patterns, it identifies dangerous arc faults caused by aging insulation, loose connections, or damaged wiring.

When abnormal arc signatures are detected, the device instantly disconnects the circuit, providing reliable protection for residential, commercial, and industrial electrical systems. Built with integrated protection, AFDD combines arc fault detection, overload protection, and short-circuit protection in a compact DIN-rail device, making it an essential upgrade for modern electrical safety standards.

• Detects series, parallel, and ground arc faults in real time
• Prevents electrical fire risks caused by insulation aging or loose wiring
• Integrated protection: arc fault + overload + short circuit
• Fast tripping response for high-risk fault conditions
• LED status indication for system diagnostics
• Remote monitoring & communication capability (RS485 / CAN)
• Compact DIN-rail installation for easy retrofit
• Suitable for residential, commercial, and industrial circuits

Smart Monitoring & System Integration

Equipped with communication interfaces such as RS485 and CAN bus, AFDD can be connected to fire alarm systems or remote monitoring platforms for real-time status visibility.

Advanced Arc Fault Recognition Technology

AFDD continuously monitors waveform distortion in voltage and current signals. It intelligently distinguishes hazardous arc patterns from normal load fluctuations, ensuring accurate detection while minimizing false trips.

Multi-Level Electrical Protection in One Device

Beyond arc fault detection, AFDD integrates overload and short-circuit protection into a single unit, reducing system complexity and improving panel efficiency.

Fast Response Fire Prevention Mechanism

Once a hazardous arc fault is confirmed, the device immediately disconnects the circuit within milliseconds, significantly reducing the risk of electrical fire escalation.
