## Long description

The Dehn DV M2 TN 255 FM is a high-performance 2-pole combined surge arrester specifically engineered for TN electrical systems. This advanced device integrates Type T1, T2, and T3 protection levels into a single unit, offering comprehensive defense against both direct lightning currents and transient switching surges. Designed for reliability, it features a built-in remote signaling contact that allows for continuous monitoring of the device status, ensuring that sensitive electrical installations remain protected against unexpected overvoltages at all times.
Advantages
This surge arrester stands out due to its multi-stage protection capability, which covers a wide range of surge events from high-energy lightning strikes to smaller switching transients. By combining three protection classes in one compact housing, it simplifies installation and reduces the space required in distribution boards. The inclusion of a remote signaling contact provides an essential diagnostic feature, enabling facility managers to receive immediate alerts if the protection module requires replacement, thereby maintaining the integrity of the electrical system without manual inspection.
Suitable for
TN-S and TN-C electrical distribution systems
Industrial and commercial electrical panels
Protection of sensitive electronic equipment and control systems
Main distribution boards where high-energy surge protection is required
When it may not be suitable
This device is specifically designed for TN systems and is not compatible with IT or TT earthing systems without appropriate modifications or additional equipment. It should not be installed in environments exceeding its specified voltage or current ratings, as this may lead to device failure or safety hazards.
Key specifications
Protection type: T1+T2+T3 combined
Number of poles: 2
System compatibility: TN systems
Maximum discharge current: 50kA
Remote signaling: Integrated contact
How to use
The device is designed for mounting on a standard DIN rail within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. The input and output terminals must be connected securely to the phase and neutral conductors, while the remote signaling contact can be wired to a building management system or an alarm indicator for remote monitoring. Ensure that the grounding connection is established with the shortest possible cable length to maintain optimal protection performance.
What to consider before purchase
Verify that your electrical system is a TN configuration
Check the available space in your distribution board for a 2-pole module
Ensure the remote signaling integration is compatible with your existing monitoring infrastructure
Confirm that the discharge capacity meets the requirements of your specific installation site
Usage recommendations
Regularly inspect the status indicator on the front of the device to ensure it remains in the operational state. If the remote signaling contact triggers an alarm, replace the protection module immediately to maintain continuous protection for your electrical equipment.
