    HM385-25T1(3P+N) A0620032

    The SPD is mainly used for lightning or other transient overvoltage surge protection oflow-voltage power supply and distribution system and electrical equipment. The product is mainly used for the fir

    • Power SPD: (II - 8/20μs)
    • Signal SPD: (II - 8/20μs)

    The SPD is mainly used for lightning or other transient overvoltage surge protection of
    low-voltage power supply and distribution system and electrical equipment.

    The product is mainly used for the first level lightning protection of a three-phase AC power supply
    system, and the multilayer graphite gap of trigger circuit is used internal.
