Surge arrester DEHNventil M2 TNS 255 FM Type 1+Type 2+Type 3 956405

Comprehensive protection of electrical installations with DEHNventil M2 TNS 255 FM

The DEHNventil M2 TNS 255 FM surge arrester is an advanced device providing multi-stage protection of electrical installations against the effects of surges, including lightning strikes. Its design combines the features of Type 1, 2 and 3 arresters, guaranteeing reliable operation in various conditions. This is an ideal solution for both installers looking for a universal product and end-users who want to protect their devices from damage.

This four-pole, modular arrester is designed for TN(C)-S networks with a rated voltage of 230/400 V and occupies only 4 modules in the distribution board. It has an integrated remote status indication contact, which facilitates monitoring its operation and quick response in the event of a failure. Rapid Arc Control (RAC) technology minimizes the risk of electric arc formation, increasing safety and device life.

High efficiency and versatility of application

DEHNventil M2 TNS 255 FM is not only protection against direct lightning strikes, but also protection against transient surges generated by electrical devices. Thanks to this, it protects sensitive receivers, such as RTV equipment, computers or home automation systems. It can be used in accordance with the Zonal Concept of Lightning Protection as a transition element between zones 0A and 2.

• Three levels of protection in one device: Type 1 + Type 2 + Type 3 – comprehensive installation protection.

• RAC technology: Ensures fast and effective limitation of follow currents, minimizing the risk of damage.

• Remote status indication: Enables current monitoring of device operation and quick response to any failures.

• High surge current capacity: Lightning impulse current (10/350 µs) is as high as 100 kA, guaranteeing effective protection even during strong atmospheric discharges.

• Compliance with standards: Meets the requirements of EN 61643-11 and DIN CLC/TS 61643-12, confirming its high quality and safety.

• Versatile application: Ideal for protecting installations in residential, commercial and industrial buildings.

This arrester is compatible with arresters from the Red/Line family and can be connected directly to end devices – providing flexibility in the design of surge protection systems. The voltage protection level below 1.5 kV ensures effective limitation of surges to a safe level for connected devices.
