Item no. 792-800

Surge suppression module for signal technology; Nominal voltage: 24 VDC; for 2 signal paths with common surge arrester; for unbalanced interfaces; Two-stage; Width: 6 mm; 2,50 mm²


Short description:

Surge protection devices for IT systems and devices in the voltage range up to 60 V (except special solutions, e.g., telephone systems with call voltage).

Overvoltage protection is also possible for DIN-35 rail-mount terminal blocks. Multi-stage surge suppression devices in rail-mount terminal blocks (792-80x Series) of just 6 mm width ensure cost-effective protection for control and bus technology (e.g. LON® network, PROFIBUS network, binary signals).


  • Protect your system against overvoltage
  • Slim, space-saving design
  • Control operational costs by preventing expensive, unplanned downtime
  • High operational reliability and system uptime


The coordination characteristics give information about the let-through energy of the overvoltage protector and the protection capacity.
