Product Description

Dehn DG M TT 2P ACI 275 FM is a modular surge arrester designed for industrial and commercial use in single-phase 230 V-TT and TN electrical systems with a maximum voltage rating of 275 volts. The unit incorporates innovative Advanced Circuit Interruption (ACI) technology, which combines a switch and spark gap within the protection module, eliminating the need for an external backup fuse and ensuring simplified installation and enhanced safety.

This surge arrester is DIN Rail mountable, supporting compact installations with the physical dimensions of 36mm in length, 90mm in height, and 77mm in depth. It is engineered to operate reliably across a broad temperature range from -40°C to 80°C, making it suitable for diverse environments.

The arrester provides high system reliability, preventing the tripping of 32 A gG fuses and possessing zero leakage current thanks to galvanic isolation afforded by the ACI switch unit. It also withstands temporary overvoltages (TOV) up to 440V AC, protecting sensitive electrical infrastructure from transient voltage spikes.

The product meets international quality and safety standards including KEMA, EN 61643-11, IEC 61643-11, and RoHS directives, ensuring compliance with stringent industrial requirements. Its design supports small connection cross-sections of up to 6 mm², optimizing wiring complexity and installation space.

Energy coordination with other arresters from the Red/Line product family ensures comprehensive surge protection in a variety of industrial, manufacturing, commercial, and electrical power distribution applications.

This surge arrester is manufactured in Germany and is supplied new to the market. Features Advanced Circuit Interruption (ACI) technology ensuring no external backup fuse is required. Compact DIN Rail mounting with dimensions 36mm length, 90mm height, and 77mm depth.
