DTE 2/485

Article number: 42 295
This product is no longer recommended for new designs, there may be a problem with its delivery in the future. Consider using an alternative product:
  • Designed for the protection of data and communication lines against longitudinal and transverse surge effects.
  • Contains both 1st and 2nd stage of protection.
  • Suitable for use in industrial applications, especially in low-voltage ESS, FDAS systems and also in measurement and control systems.
