## Long description

Dehn DG M TN 275 is a modular surge arrester designed for single-phase TN systems (2+0 configuration) to protect 230 V AC installations. The device is a prewired complete unit composed of a base part and plug-in protection modules, housed in a red thermoplastic enclosure with compact dimensions suitable for installation in distribution and photovoltaic accessory panels. It is intended for coordination with other devices of the same product family and provides high discharge capacity and reliable monitoring.
Advantages
The unit offers energy coordination with other arresters from the Red/Line family and high discharge capability thanks to heavy-duty zinc oxide varistors and integrated spark gaps. It includes a "Thermo Dynamic Control" monitoring device for enhanced reliability and a module locking system with a release button that allows tool-free replacement of protection modules. The product has been vibration and shock tested according to EN 60068-2 and is certified to CE, VDE and UL standards.
