ALFDDLE Electrical Fireproof Current Limiting Protector

The AFDDLE is an intelligent electrical fire protection device integrating arc fault detection and advanced Type B+ residual current protection. Its dedicated AI chip enables precise identification of complex faults. It provides comprehensive protection against overloads, short-circuits, and voltage abnormalities. The key innovation is Type B+ protection, detecting all leakage currents (AC, pulsating, and smooth DC) beyond traditional types. This makes it essential for modern applications with power electronics, offering a complete safety solution for residential, commercial, and industrial use to prevent electrical fires.

    Product Details

    Product Descriprion

    The AFDDLE is an advanced electrical fire protection device combining arc fault detection (AFDD) and Type B+ residual current protection in one integrated unit. Its core utilizes a dedicated protection chip with AI heterogeneous computing and a multi-core CPU, enabling high-speed data acquisition and intelligent algorithm analysis for accurate fault identification.
    A key advantage is its Type B+ residual current detection, which surpasses traditional Type AC, A, F, and even standard Type B protectors. It comprehensively detects AC, pulsating DC, and smooth DC leakage currents, addressing risks from modern power electronics like EV chargers, solar inverters, and variable-speed drives.
    The device provides multi-functional protection including arc fault detection, electronic overload protection, configurable over/under-voltage protection (50-440V range), and a high short-circuit breaking capacity of 6kA. With self-check capabilities and current zero-crossing tripping technology, it ensures reliable operation and equipment safety. This integrated solution is specifically designed to prevent electrical fires in increasingly complex electrical environments across residential, commercial, and industrial applications.
