Surge arrester DEHNguard SMP TNS 275 Type 2+Type 3 942402

Electrical installation protection with DEHNguard SMP TNS 275

This multi-pole surge arrester, DEHNguard SMP TNS 275, is a key element in ensuring the safety and reliability of electrical installations. Designed as a combination of Type 2 and Type 3 arresters, it offers comprehensive protection against the effects of surges, both impulsive (e.g., lightning strikes) and transient.

This is particularly important in residential, commercial, and industrial buildings where sensitive electronic devices require robust protection.

This arrester is used in TN-S networks, and its modular design with a double-pole plug-in terminal facilitates both branched and series connections. This makes the installation flexible and easy to adapt to specific needs. The "Thermo Dynamic Control" monitoring and disconnecting device provides an additional level of safety, automatically disconnecting the arrester in the event of a fault and signaling the need for replacement.

Key features and benefits:

• Versatile protection: The combination of Type 2 and 3 provides effective protection against various types of surges, minimizing the risk of equipment damage.
• Easy installation: The modular design and plug-in terminals significantly simplify the installation process, saving time and labor costs. This will be appreciated by both installers and individuals who independently ensure the safety of their installation.
• High reliability: The "Thermo Dynamic Control" monitoring and disconnecting device guarantees safe operation and signals the need for replacement in the event of a failure – ensuring long-term protection.
• Compliance with the zone concept of lightning protection: Ideally suited for use as a transition between zones 0B – 1 and higher, providing optimal protection for the entire installation.
• Solid construction: Made of high-quality materials, which translates into durability and resistance to environmental conditions.
