Dehn Modular Surge Protector 255V AC Maximum Voltage Rating 100 kA Maximum Surge Current Lightning Arrester DV M TNS 255 FM

Dehn DV M TNS 255 FM is a modular surge protector designed for industrial and commercial electrical installations to safeguard equipment from transient voltage surges and lightning strikes. Rated for a maximum voltage of 255V AC and capable of handling surge currents up to 100 kA, this lightning arrester offers reliable protection with minimal downtime.

The device integrates type 1 and 2 prewired spark gap technology, combining lightning current and surge arresters within a modular base and plug-in configuration. The RADAX Flow follow current limitation enhances system reliability by preventing unnecessary fuse trips during faults up to 50 kA, making it suitable for high short circuit currents.

Easy maintenance is ensured through a lock-in system for protection modules, allowing quick replacements without tools. The unit includes operating state and fault indication flags, with optional remote contact functionality in the base for monitoring.

Mountable on DIN rails, the surge protector is designed to coordinate with Dehn Redline products in compliance with BS7671 amendment 1, meeting advanced safety and performance standards. It operates reliably in harsh environmental conditions with a temperature range spanning from -40°C to 60°C.
