TRSS-RJ45/8-E Outdoor Ethernet Surge Protection Device

Date：2026-04-18

The TRSS-RJ45/8-E is Thor's outdoor-rated Ethernet surge protection device, engineered for permanent installation in exposed environments where standard indoor SPDs fail. With an IP68 enclosure, full Gigabit Ethernet compatibility, and dual-line protection for both data and PoE power, it is the purpose-built solution for outdoor IP camera networks, industrial Ethernet infrastructure, and PoE-powered field devices.

Built to a Higher Specification

The TRSS-RJ45/8-E is built to a specification that goes beyond the minimums. Response time is rated at less than 25 nanoseconds — the clamp engages before a surge transient can reach network interfaces.

The operating temperature range of -40°C to +85°C covers conditions from arctic winters to direct sun exposure in hot climates, well beyond the 0°C to 40°C rating typical of standard indoor SPDs.

PoE protection extends to 57V DC pair-to-pair, covering PoE++ deployments and protecting both the data circuit and the power supply within a single inline device.

Typical Applications

•Outdoor IP surveillance systems — Protects Ethernet cables running from pole-mounted or rooftop cameras back to indoor NVRs and switches. A single lightning event on an unprotected cable run can take out multiple camera units simultaneously; the TRSS-RJ45/8-E breaks that conduction path before the surge reaches connected equipment.

•Industrial and infrastructure networks — Suitable for factory floors, port facilities, parking structures, and logistics yards where Ethernet cables run across open ground or between separate buildings. The -40°C to +85°C operating range and IP68 sealing cover conditions from arctic winters to direct sun exposure in summer — reliable across extreme seasonal temperature swings.

•PoE-powered outdoor devices — Wireless access points, VoIP intercoms, and LED controllers draw both power and data through the same RJ45 connection. The TRSS-RJ45/8-E protects all eight pins — data lines and PoE pairs — in a single inline device.

•Building-to-building connections — Any Ethernet cable spanning two structures with independent grounding systems is exposed to ground potential rise during lightning events. Installing the TRSS-RJ45/8-E at each transition point is the standard mitigation for this risk.

Why IP68 Matters for Outdoor SPD Installation

An SPD without meaningful ingress protection degrades silently in outdoor conditions. Condensation, temperature cycling, and direct rain work their way into the housing over months, corroding internal MOV and GDT components. The failure is insidious — the device continues passing network traffic normally until a surge event reveals that protection is no longer functional.

The TRSS-RJ45/8-E is sealed to IP68 — fully dust-tight and rated for continuous immersion beyond one meter. The protection level at installation is the protection level five years later.
