Dehn guard MP TT 275

The DEHNguard MP TT 275 is a multipole surge arrester developed according to the standards EN 61643-11 and DIN EN 62305-4. It provides reliable protection for low-voltage consumer installations against surges that can be caused by lightning strikes or other electrical disturbances. The surge arrester is designed for use in TNS and TT networks and is particularly well-suited for mounting on a DIN rail. With a nominal discharge current of 20 kA and high device safety thanks to the integrated arrester monitoring with Thermo-Dynamic-Control, it ensures effective dissipation of voltage spikes. The protection modules are individually replaceable, allowing for easy maintenance, and no external pre-fuse is required. The DEHNguard MP TT 275 is therefore an optimal solution for protecting electrical installations in various applications.

• Modular design with individually replaceable protection modules
• High device safety through Thermo-Dynamic-Control
• No need for external pre-fuse
• Operating temperature range from -40°C to +80°C
• Lightning impulse current of 40 kA for additional protection.
