    ZGLEDUN Series LD-MD SPD Surge Protection Devices with the following features.

    • High-energy surge protection

    • Remote signal alarm interface

    • Failure detection indicator

    • Standard modular installation

    • Built-in instantaneous overcurrent circuit breaker

    • Pluggable replacement modules

    • Single module maximum discharge current 20-80KA (8/ 20μs),

    • Response speed: 10-9s level.

    LD-MD series T2 surge protector SPD is designed according to IEC and GB standards. It has a strong surge discharge capacity and the maximum discharge current per unit is 20-80KA (8/20μs). It’s suitable for all levels of protection of low-voltage power distribution systems, and can be selected according to different power distribution systems (TT/TN/IT) with multiple combinations.

    Application Places:

    LD-MD-80, LD-MD-60: The main power distribution cabinet of the building where the power line is shielded and ground input, the distribution box with outdoor input and output lines in the building, and the outdoor power distribution cabinet/distribution box

    LD-MD-40: Building floor distribution box

    LD-MD-20: Distribution boxes for important electrical equipment in buildings, such as computer room distribution boxes and residential distribution boxes
