Surge Arresters – Type 2

DEHNguard PCB
• Base for DEHNguard protection modules to be mounted on
and integrated in PCBs
• Optimal integration of a type 2 arrester in devices
• Easy and flexible use for all circuit configurations
• Proven DEHNguard modules ensure high performance
• Coded base and protection module guard against installing
an incorrect module
• Version with and without remote signalling contact for the
monitoring device
• Versions for maximum requirements on clearances and
creepage distances
• Versions for other DEHNguard protection modules available
on request
For integrating a type 2 arrester on the printed circuit board of a device to provide
surge protection. For installation in conformity with the lightning protection zone
concept at the boundaries from 0B– 1 and higher.
