## Summary description

Surge arrester by DEHN + Söhne, model DR M 2P 255 FM, designed for 230 V nominal input voltage and 50 - 60 Hz AC input frequency with terminal connections. Features a fast response time of 0.000025 ms and is housed in a durable red thermoplastic enclosure. Certified with CE, KEMA, VDE, UL, and CSA standards, this 2-pole protective device is ideal for electrical installations requiring reliable transient overvoltage protection and fault monitoring.

## Long description

The Surge Arrester DEHN DR M 2P 255 FM is a two-pole protective device designed for electrical installations requiring reliable transient overvoltage protection and fault monitoring. Manufactured by DEHN + Söhne, this surge arrester consists of a base part and a plug-in protection module featuring a floating remote signalling contact. It operates at a nominal input voltage of 230 V with an AC input frequency of 50 to 60 Hz. Housed in a durable red thermoplastic enclosure, the device offers a fast response time and is built to withstand demanding conditions.
Advantages
This surge arrester provides a high discharge capacity thanks to its heavy-duty zinc oxide varistor and spark gap combination. It supports energy coordination with other arresters of the Red/Line product family for comprehensive system protection. The operating state and fault status are clearly indicated by a green and red indicator flag in the inspection window. Featuring a narrow modular design according to DIN 43880, it saves valuable space in control panels. Furthermore, the module locking system with a release button allows for easy replacement of protection modules, and the unit is vibration and shock-tested according to EN 60068-2 standards.
Suitable for
Electrical installations requiring 230 V AC transient overvoltage protection
DIN rail mounted electrical distribution boards and control panels
Systems needing remote fault monitoring via a floating signalling contact
Industrial and commercial setups requiring compliance with CE, KEMA, VDE, UL, and CSA standards
When it may not be suitable
This surge arrester is not designed for direct current applications outside its specified AC parameters, nor is it suitable for electrical systems operating at voltages significantly different from the 230 V nominal input rating. It should not be installed in environments that exceed its specified mechanical and environmental testing limits.

230 V nominal input voltage
50 to 60 Hz AC input frequency
0.000025 ms response time
Red thermoplastic enclosure material
DIN 43880 modular design
Green and red operating state and fault indicator flag
Floating remote signalling contact

How to use
Installation should be performed by a qualified electrician in accordance with local electrical safety regulations and wiring standards. Mount the surge arrester onto a standard DIN rail within the electrical enclosure. Connect the incoming AC lines to the terminal connections, ensuring proper integration with the system earth and other coordinated protective devices. Utilize the floating remote signalling contact if remote fault monitoring is required. Regularly check the mechanical indicator window to verify the operating status of the protection modules.
What to consider before purchase
Verify that the nominal voltage and frequency of your electrical system match the 230 V and 50 to 60 Hz specifications
Check available space in your distribution board to accommodate the narrow modular DIN-rail design
Confirm whether remote signaling capabilities are required for your maintenance workflow
Ensure installation environment complies with standard vibration and shock resistance parameters
Usage recommendations
Always disconnect power to the electrical distribution board before installing, inspecting, or replacing the surge arrester modules. Routinely inspect the indicator window for status changes and replace any triggered plug-in modules promptly using the module release button to maintain uninterrupted protection.
