DEHN Lightning & Surge Protection Systems

DEHN develops lightning and surge protection solutions for electrical and electronic systems exposed to transient overvoltages caused by lightning events and switching operations. Correct surge protection helps coordinate the protection of power, industrial, building and electronic installations according to the electrical system and installation location.

The DEHN Red/Line portfolio includes protective devices for power-supply systems up to 1,000 V AC and 1,500 V DC, depending on the selected product. The range covers Type 1, Type 2 and Type 3 surge protective devices for different stages of the protection concept.

Available product types include lightning-current arresters, surge arresters and combined arresters. Representative DEHN product families include DEHNguard, DEHNshield, DEHNsecure and related solutions designed for different network configurations and protection requirements.

Applications include industrial installations, buildings, power systems, photovoltaic systems, telecommunications and infrastructure. Selection should consider network type, nominal system voltage, expected surge environment, installation point and the required SPD type or protection stage.

Sea Star International can assist with identification and sourcing of DEHN lightning and surge protection equipment based on the electrical single-line diagram, system voltage, network configuration, required protection concept and project specification. This helps ensure that the selected protective device is technically matched to the intended installation rather than chosen only by product family.
