DTNVE 2/30/0,5

Article number: 42 309
  • Designed for the protection of data and communication lines against longitudinal and transverse surge effects.
  • The inserted series impedance consists of inductors, which allow the higher nominal current permanently flow through the protection. This predetermines the equipment for protection of the given power supply line of the system.
  • It can be used for the protection of analog data lines using the current loop 4 to 20 mA.
  • Not suitable for digital data transmission with high transmission speed.
