For measurement, control and regulation circuits, and twisted pairs

DIN-Rail Universal 4-Pole Surge Protective Device

Universal 4-wire, DIN-Rail mounted surge arresters provide effective protection with minimum space requirements and are designed for stringent requirements on the availability of measurement, control and regulation circuits, and bus systems.

  • Function-optimized design for safe use and easy installation
  • Module removal without signal interruption via “make-before-break” circuitry
  • 0-180V BSPD0180DINL automatically adjusts to system operating voltage and can protect data circuits of different voltages to a maximum 100mA load current
