• Protects 4 pairs (8 cores) for 10GBase-T Ethernet up to 10 Gbps
• Nominal voltage: 48 V DC; max continuous operating voltage: 57 V DC
• Nominal discharge current (line-line and line-PE): 1 kA (8/20 µs) each
• Total discharge current: 20 kA (8/20 µs)
• Voltage protection level: ≤ 250 V line-line, ≤ 600 V line-PE at 1 kA
• Cut-off frequency: > 1.2 GHz, ensuring signal integrity for high-speed data
• PoE+ (IEEE 802.3at) compatible up to 57 V
• Connection: RJ45 jack to RJ45 plug, plug-in module for DEHNpatch base
• Operating temperature: -40 °C to +80 °C; protection class IP20; plastic housing

Why choose it

The DPA M CLE RJ45B 48 combines robust surge protection with high-frequency performance, making it suitable for modern gigabit and 10-gigabit networks. Its compact plug-in design allows quick replacement without rewiring, minimizing downtime. The module's low voltage protection levels safeguard sensitive network equipment from damaging transients, while its wide temperature range ensures reliable operation in harsh environments.

Ideal use cases

• Protecting Ethernet switches, routers, and servers in data centers
• Shielding IP cameras, wireless access points, and industrial controllers
• Securing PoE+ powered devices such as VoIP phones and access points
• Retrofitting existing DEHNpatch installations with high-speed protection

Good to know

The module is designed for use with DEHNpatch base units and must be installed by qualified personnel. It is not a standalone device. Ensure proper grounding of the base unit for effective surge diversion. The plastic housing provides insulation and is rated IP20 for indoor use.
