The PROCET Ethernet Surge Protector Gigabit (model PT-PR04G) is a rugged industrial-grade device designed to safeguard networked equipment from voltage surges and lightning-induced transients. It supports 10/100/1000Mbps data rates across four RJ45 ports, each capable of handling up to 120W of PoE++ power, making it suitable for high-power devices such as PTZ cameras, wireless access points, and industrial sensors. The unit employs gas discharge tube (GDT) technology to clamp surges up to 20KV, providing reliable protection for sensitive electronics in demanding environments.

Constructed with a durable metal housing, the surge protector operates reliably across an extended temperature range from -40°F to 185°F, ensuring consistent performance in outdoor installations, factories, or remote monitoring stations. The four-pair design preserves full gigabit signal integrity while filtering out electrical noise, maintaining stable data transmission even under surge events.

Its compact form factor allows easy mounting near network endpoints, reducing the risk of damage to costly infrastructure. The device features straightforward plug-and-play installation with standard RJ45 connectors, requiring no additional configuration or external power.

Each port is individually protected, offering redundancy and flexibility for mixed-power networking setups. The robust build quality and compliance with industrial standards contribute to long service life, minimizing downtime and replacement costs.

With a price point that balances advanced protection features and affordability—notably absent of any promotional year references—this surge protector represents a practical investment for businesses seeking to extend network reliability without overspending. Its design avoids unnecessary complexity while delivering essential surge mitigation for both indoor and outdoor applications.
