The TRSS-RJ45/4 is a professional-grade Ethernet surge protector specifically engineered for 10/100M networks (LAN) that require targeted 4-line protection for data pins 1, 2, 3, and 6. It serves as an ideal solution for industrial environments where PoE functionality is not required, ensuring high-speed data integrity without unnecessary complexity.
This device features a standard 35mm DIN-rail mounting system, allowing for seamless integration into server racks and indoor distribution boards. It effectively shields connected workstations, routers, and server equipment from transient overvoltages caused by line inductance or earth potential fluctuations. To ensure long-term stability within industrial control cabinets, the unit is housed in a durable, IP20-rated PA66 enclosure.
As a high-capacity surge protection device, the TRSS-RJ45/4 offers superior discharge capability and an instantaneous response time to maintain continuous system uptime. It is designed for series connection, providing a stable voltage protection level (Up) that is critical for safeguarding sensitive network interfaces against electrical transients.
The TRSS-RJ45/4 is fully compliant with international standards IEC 61643-21 and EN 61643-21.
