Dimension drawing DCO RK E
Basic circuit diagram DCO RK E
Finely limiting surge protective device with efficient diodes to earth for two single lines with common
reference potential as well as unbalanced interfaces.
• Surge protection in the form of blocks
• Can be subjected to high nominal currents
• For installation in conformity with the
lightning protection zones concept at
the boundaries from 1 – 2 and higher
