Delock RJ45 Network Surge Protector Cat.6A, PoE++ Compatible, 10 Gbps, Shielded, Black

In a busy office, a network switch and a connected PC are vulnerable to voltage spikes from lightning or switching operations. The Delock RJ45 surge protector sits inline between the wall outlet and your device, clamping transient overvoltages on all 8 lines to protect expensive network equipment. It supports 10 Gigabit Ethernet and Power over Ethernet up to IEEE 802.3bt, so it works with modern PoE++ devices like IP cameras and access points.

Why choose it

This surge protector combines high-speed data integrity with robust surge protection. The low insertion loss and high return loss ensure that your network performance remains unaffected, while the fast response time and high discharge capacity protect against even severe transients. The shielded metal housing and included grounding cable provide reliable earthing, and the wide operating temperature range makes it suitable for harsh environments.

Ideal use cases

• Protecting network switches, routers, and PCs in offices and homes
• Safeguarding PoE-powered devices such as IP cameras, VoIP phones, and wireless access points
• Industrial applications where network equipment is exposed to electrical noise or lightning
• Outdoor installations where long cable runs increase surge risk

Good to know

The protector is backward compatible with Cat.6, Cat.5e, and Cat.5 cabling. It is easy to install: simply connect it between the network cable and the device, and attach the grounding wire to a suitable earth point. For best protection, install the surge protector as close as possible to the device to be protected.
