Surge Protector Exertis Connect 253187 for RJ45 Cat.6A cables, indoor

Surge Protector Exertis Connect 253187 for RJ45 Cat.6A cables is an inline indoor device engineered to protect Ethernet cabling and connected network equipment from transient overvoltage events. It is intended for installation on Cat.6A RJ45 lines in structured cabling environments such as offices, server rooms and network distribution points. The protector intervenes on voltage spikes traveling along the data pair conductors, helping to prevent damage to switches, routers, IP phones and other connected devices while preserving signal integrity for high-speed data transmission.

Advantages

This surge protector provides point-of-use protection without altering the Cat.6A cable termination method or adding significant insertion loss. It is compact and designed for indoor mounting close to the protected equipment, reducing the exposure of connected devices to transient voltage. The device supports the electrical characteristics required for Cat.6A throughput, enabling continued operation at the intended data rates while offering a layer of protection against common-mode and differential surge events.

Suitable for

• Protecting switches, routers and access points in office networks
• Securing connections to IP phones and VoIP endpoints
• Protecting server room patch panels and edge network hardware
• Use in structured cabling runs within indoor commercial and institutional buildings

Key specifications

• Connector type: RJ45 inline connections compatible with Cat.6A cabling
• Application environment: Indoor use
• Protection target: Ethernet data pairs (differential and common-mode transient suppression)
• Designed to maintain Cat.6A signal performance for high-speed data transmission
• Form factor: Compact inline module for close-to-equipment placement

How to use

Install the surge protector inline between the incoming Cat.6A cable and the device or patch panel port to be protected. Ensure the RJ45 connectors are fully inserted and that connections follow standard wiring practices. Place the unit as close as possible to the protected equipment to limit exposure of downstream devices to surges. No user configuration is required; the protector operates passively and continuously to attenuate transient voltages.

Usage recommendations

To maximize effectiveness, use one protector per protected endpoint and position it near the equipment it protects. Verify that the surrounding installation remains dry and that connectors are free of corrosion or mechanical damage. Periodically inspect the protector and cabling after severe electrical events and replace the unit if physical signs of stress are present or if network performance is degraded.
