DEHNguard TT 2P 5 340 Surge Arrester – Type 2
The DEHNguard TT 2P 5 340 is a modular two-pole surge arrester designed to protect electrical installations against transient overvoltages. The device is classified as a Type 2 SPD according to IEC 61643-11 and is suitable for use in TT and TN systems in a 1+1 configuration.
With its compact design of only 2 DIN modules, the surge arrester can be easily installed in distribution boards where space is limited. An integrated fault indication allows quick visual status monitoring. The device is energy-coordinated with arresters from the DEHN Red/Line product series, making it ideal for coordinated lightning and surge protection systems.
