Surge protection device DEHNguard M TT 2P 275 Type 2 952110

Electrical installation protection with DEHNguard M TT 2P 275

The DEHNguard M TT 2P 275 surge arrester is a key element ensuring the safety of electrical installations in residential and commercial buildings. Designed to work with TT and TN networks at 230V, it effectively protects against the effects of atmospheric overvoltages and network disturbances. The device is modular, two-pole and ready for immediate mounting on a DIN rail.

This Type 2 surge arrester, compliant with EN 61643-11, is an integral part of the Zonal Concept of Lightning Protection, ensuring a smooth transition between protection zones. Its construction based on a replaceable protective module and an advanced "Thermo Dynamic Control" monitoring and disconnecting device guarantees reliability and long-term protection. A damage indicator facilitates quick identification of the need for module replacement.

Key features and benefits:

• Effective protection: Rated discharge current of 20 kA and short-circuit withstand capacity of 50 kArms provide solid protection against overloads and short circuits.

• Versatile application: Ideal for TT and TN networks at 230V, a width of only 2 modules allows for easy integration with existing switchboards.

• Safety and reliability: The "Thermo Dynamic Control" monitoring and disconnecting device disconnects the arrester when permissible parameters are exceeded, minimizing the risk of damage.

• Ease of use: Replaceable protective module simplifies maintenance and replacement, and the optical status indicator informs about the need for intervention.

• Compliance with standards: Meets the requirements of EN 61643-11 and enables energy coordination in accordance with DIN EN 62305-4 – which is important for designers and installers of lightning protection systems.

• Protection level: Voltage protection level up to 1.5 kV minimizes the risk of damage to connected electronic devices.

The DEHNguard M TT 2P 275 surge arrester is an investment in the safety of the electrical installation and the peace of mind of users. Its solid construction and advanced features make it a reliable solution for any home or business. Installation is simple and intuitive, and the compact dimensions facilitate integration with existing electrical infrastructure.
