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

This surge protector is mainly used for lightning protection of low voltage power supply and distribution systems
and electrical equipment or other transient overvoltage surge protection.

The product has built-in over-temperature and over-current protection to provide last-level surge
protection for DC power distribution systems. The product adopts 35mm DIN rail mounting method. The
module can be replaced independently for easy installation and maintenance. It has a remote signaling
interface (dry contact) for remote monitoring of the surge protector status
