## Long description

The Dehn DR M 2P 255 FM is a high-performance Type 3 surge arrester engineered to provide reliable protection for sensitive electronic equipment in 230 V AC electrical systems. This two-pole device consists of a robust base part and a plug-in protection module, ensuring efficient operation and ease of maintenance. Designed for professional electrical installations, it utilizes a heavy-duty zinc oxide varistor and spark gap combination to deliver high discharge capacity, effectively safeguarding connected devices against transient overvoltages.
Advantages
The primary advantage of this surge arrester is its modular design, which allows for the quick and easy replacement of protection modules via a dedicated release button. The device features a clear visual status indicator, displaying green or red flags to signal the operating state or potential faults. Its compact, narrow form factor adheres to DIN 43880 standards, making it ideal for space-constrained distribution boards. Furthermore, the unit is vibration and shock-tested to ensure long-term durability and consistent performance in demanding environments.
Suitable for
Protection of sensitive electronic devices in 230 V AC circuits
Integration into professional electrical distribution systems
Applications requiring energy coordination within the Red/Line product family
Installations where remote signaling of surge protection status is necessary
When it may not be suitable
This device is specifically designed as a Type 3 surge arrester for fine protection and is not intended to serve as the primary lightning protection or coarse surge protection for an entire building. It should be used in conjunction with upstream Type 1 or Type 2 arresters to ensure a complete protection concept.
