    Power SPD- C-level Power Surge Arrestor

    M1L320-40II(3P+N) A0520112?

    The surge protector is mainly used in surge protection for lightning or other transient over-voltage from low voltage power distributionsystem and electrical equipment. Product is built-in overheating

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

    The surge protector is mainly used in surge protection for lightning or other transient over-voltage from low voltage power distribution
    system and electrical equipment.

    Product is built-in overheating and over-current protection function, which can provide low voltage power distribution system and electric
    equipment with class C (
    level classification test) lightning protection. This type adopts to 35 mm DIN TTW Guide installation.The
    surge protection module can be changed independently, which possesses ease of installation and maintenance.With a remote
    communication alarm interface (dry contact), it is convenient to monitor the status of the SPD.
