    Product Features & Advantages

    Safe and reliable, preventing accidents before they happen: With precise overload and short-circuit dual protection functions, it can monitor circuit anomalies in real time and respond quickly, significantly reducing the risk of electrical fires at the source and building a solid defense line for power safety.

    Manual control, flexible operation and maintenance: Supports stable and reliable manual on/off operation and can be used directly as an isolating switch. When equipment needs to be repaired or maintained, it can quickly disconnect the circuit, providing a safe operating environment for operators and improving operational convenience.

    Easy operation and quick reset: After the circuit fault is eliminated, there is no need for complicated operations. Just turn the operating handle back to the "on" position to easily restore power supply, reducing power outage downtime and ensuring power continuity.

    Modular design and efficient installation: The modular structure with standardized dimensions can be directly adapted to the distribution board mounting rails, which not only effectively utilizes the installation space but also simplifies the installation process and subsequent maintenance steps, reducing overall construction and operation and maintenance costs.
