Product details
The DEHNrail DR M 2P 255 is the arrester you fit last in the chain and closest to the equipment that matters. Rated for a 25A load current on a 230V single-phase supply, it takes one DIN module and cuts the residual surge energy that gets past upstream protection to a level modern electronics can live with.
Key features
- Two-pole Type 3 arrester in a single DIN module, so it fits where space is tight
- Plug-in protection module on a base element - replace the module, keep the wiring
- Green/red operating state window gives an immediate visual end-of-life check
- Voltage protection level of 1250V L-N and 1500V L/N-PE
- Energy-coordinated with DEHN Red/Line Type 1 and Type 2 arresters upstream
Typical applications
Fit it in the local distribution board, control panel or fused connection unit feeding the load itself: PLC and instrumentation racks, building management outstations, EPOS and IT equipment, CCTV and access control, lift and door controllers, and laboratory instruments. Its 25A nominal load current means it can sit in series in the supply to a single item of plant as well as in parallel on a final circuit.
Compliance
Tested as a Type 3 device to EN 61643-11 and Class III to IEC 61643-1, with KEMA, VDE, UL, VdS and CSA approvals, a UL 94 V-0 enclosure and IP20 protection. BS 7671 requires transient overvoltage risk to be assessed, with coordinated protection fitted where the consequences justify it.
