Electrical installation protection with DEHNguard M TT 275

The DEHNguard M TT 275 surge arrester is a reliable device used to protect electrical installations from the effects of overvoltages, both caused by lightning strikes and network disturbances. It is a key element of every installation where safety and power supply continuity are important. The device is designed for use in TT and TN-S networks with a rated voltage of 230/400 V.

This four-pole arrester, consisting of a base and a replaceable protective module, provides comprehensive protection. Thanks to the use of a "Thermo Dynamic Control" monitoring and disconnecting device, it guarantees high reliability and indicates the need to replace the module after a discharge. This is particularly important for installers who can quickly identify a damaged element and restore full system functionality.
