Dehn Modular Surge Protector Lightning Arrester 255V AC Maximum Voltage 50kA Maximum Surge Current DV M TN 255

Dehn DV M TN 255 modular surge protector is an advanced lightning arrester designed for industrial and commercial electrical installations. It provides robust protection against transient overvoltages caused by lightning strikes and switching operations. This surge protector features a type 1 and 2 prewired spark gap combined lightning current and surge arrester, consisting of a base and plug-in modules.

Mounted easily on DIN rails, the device allows quick replacement of protection modules without tools, using a lock-in system. The built-in state and fault indicator flag, along with optional remote contact in the base, ensures clear operational status monitoring. The surge protector ensures maximum system availability and reliability through RADAX Flow follow current limitation technology.

This model is engineered to handle a maximum voltage of 255V AC and a maximum surge current of 50kA, with a discharge capacity of 100kA using a 10/350 microsecond lightning waveform. It is capable of withstanding short circuit currents up to 50kA without triggering 20amp gL/gG fuses, ensuring uninterrupted operation in harsh electrical environments.

The device operates reliably in temperatures ranging from -40°C to 60°C and measures a compact 90mm in length, 66mm in height, and 72mm in depth, making it suitable for tight electrical panel installations. It is compliant with major international standards including VdS, RoHS, KEMA, UL, and VDE, reflecting high safety and quality benchmarks.

Typical applications include industrial, manufacturing, commercial, and residential electrical systems where protection against lightning-induced surges is critical. The Dehn DV M TN 255 is fully coordinated with other Dehn Redline series products to meet BS7671 amendment 1 and BSEN 62305 standards for surge protection. It is manufactured in Germany, assuring premium quality engineering.

Type 1 and 2 combined lightning current and surge arrester modules ensure comprehensive protection. DIN rail mount design enables fast installation and module replacement without tools. Operating state and fault indication improves system maintenance and monitoring.
