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.
