Product Description
Dehn DV M TNS 255 Modular Surge Protector is a robust lightning arrester and surge protection device engineered for industrial and commercial applications requiring reliable safeguarding of electrical and electronic equipment. It operates at a maximum voltage of 255V AC and withstands surge currents up to 100kA, effectively protecting systems from destructive power surges caused by lightning or switching transients.
The modular design features a prewired Type 1 and Type 2 combined arrester with a lock-in system that simplifies replacement and maintenance without tools. It is designed for DIN rail mounting, ensuring fast and secure installation in electrical panels.
Its RADAX Flow technology limits follow current, enhancing system uptime and protecting against fuse tripping up to 50kA short circuits, while an indicator flag indicates operating state and faults, with an optional remote signalling contact to integrate with monitoring systems.
Engineered for harsh environments, it operates reliably from -40°C to 60°C. The device complies with multiple international standards including RoHS, KEMA, UL, VDE, and VdS, and is designed for coordinated use with other Dehn Redline products per BS7671 amendment 1.
Typical applications include industrial electrical installations, manufacturing plants, commercial buildings, and critical infrastructure requiring surge protection and lightning arrest capabilities.
