OBO ND-CAT6/E-B Net Defender protezione da sovratensione per classe E/CAT6 58V grigio argento 5081804

Protect your Ethernet networks from damaging voltage surges with the OBO ND-CAT6/E-B Net Defender. This surge protector is engineered for Class E/CAT6 cabling, ensuring reliable data transmission up to 10 Gigabit Ethernet while safeguarding connected equipment from transient overvoltages.

Who is it for

Ideal for network administrators, IT professionals, and facility managers who need to protect critical network infrastructure in commercial or industrial environments. It is particularly suited for installations where PoE+ devices are used and where space is limited.

Main features

• Designed for CAT6 / Class E networks, supporting speeds up to 10 Gigabit Ethernet.
• PoE+ compatible, allowing protection of powered devices without disrupting data flow.
• Nominal voltage of 48 V DC with a maximum continuous operating voltage of 58 V DC.
• High discharge capacity: nominal 1 kA, maximum 2.5 kA (8/20 µs).
• Low protection levels: line-line ≤ 150 V, line-earth ≤ 500 V.
• Wide frequency range up to 250 MHz with minimal insertion loss (≤ 0.3 dB).
• Compact die-cast zinc housing in silver-grey for durability and easy identification.
• Flexible mounting: direct mounting or DIN rail with adapter.

Tips

For optimal protection, install the Net Defender as close as possible to the equipment you wish to protect. Ensure that the grounding connection is properly established to achieve the specified protection levels. When using PoE+, verify that the total power budget does not exceed the protector's capabilities.
