Eaton B110-SP-POE-1 – In-Line Ethernet PoE Surge Protector

Product Overview

The Eaton B110-SP-POE-1 is an in-line Ethernet surge protector built for Power over Ethernet (PoE) installations, meeting 802.3af and 802.3at IEEE standards while supporting data speeds up to 1 Gbps. It protects connected network and PoE-powered equipment from surges and electrostatic discharge without requiring software or an external power supply. This makes it a practical safeguard for PoE cameras, access points, and other network devices exposed to unpredictable power conditions.

Product Description

Installed directly in the Ethernet run between a PoE source and a powered device, the B110-SP-POE-1 clamps voltage spikes and dissipates electrostatic discharge before they reach connected equipment, all while passing through both data and PoE power. Compliance with 802.3af and 802.3at standards ensures compatibility with standard and PoE+ powered devices such as IP cameras, wireless access points, and VoIP phones. Supporting data rates up to 1 Gbps means it will not restrict throughput on typical Gigabit Ethernet network segments. Because the unit requires no software or external power supply, it can be added to an existing PoE cable run in seconds during installation or a maintenance window. It is well suited to home and corporate security camera systems, home theater installations, trade show setups, and digital signage networks where PoE-powered equipment is exposed to surge risk from nearby lightning strikes or unstable power. IEC compliance and TAA status support its use in both general commercial deployments and government network installations. For facilities with PoE-powered security cameras or access points mounted outdoors or in exposed locations, this in-line protector adds a low-cost layer of defense against a common cause of port and device failure. It is a simple, low-maintenance accessory to specify anywhere PoE equipment needs additional surge protection.
