DEHN DIN-rail mounted surge protective devices set new standards for safety and ease of use. The UL 1449 4th Edition certification for these SPDs make them ideal for use with all common power systems and electrical panel applications in the United States and Canada. The DEHNguard surge protectors are available for use with 1-phase, 3-phase Wye, 3-phase Delta, and 3-phase High-leg Delta electrical systems. The DEHNrail family is ideal for protecting terminal equipment in industrial electronics environments. The DEHNpatch family fulfill requirements for universal Ethernet, industrial Ethernet, Power over Ethernet, and other general applications up to the Gbit range. The DEHNpipe family mounts directly onto a field device, and their corrosion-resistant stainless steel housing makes them ideal for potentially explosive atmospheres, intrinsically safe applications, or for use inside a flameproof enclosure. Replacement protection modules are available for DEHNguard and DEHNrail SPDs.
