WJ Furse Surge Suppressor Unit Telephone Line Protector 296V Maximum Voltage 20 kA Maximum Surge 7TCA085400R0171 ESP TN

WJ Furse 7TCA085400R0171 ESP TN Surge Suppressor Unit is a specialized telephone line protector designed for high-performance lightning surge protection on twisted-pair communication lines commonly used in industrial process control, modems, and communication interface equipment. With a maximum voltage rating of 296V and the ability to handle surge currents up to 20 kA, this unit ensures robust defense against transient voltage spikes and lightning-induced surges.

Engineered to deliver full mode protection with very low let-through voltage compliant with BS EN 62305 standards, it supports continued operation of protected equipment even under partial lightning current conditions. The device is encased within a flame retardant ABS housing, offering enhanced safety and durability in demanding industrial environments.

This surge suppressor features color-coded terminals for easy installation and uses an integral earthing plate with a CME kit to provide superior earthing connection. It can be mounted readily on DIN rails using the built-in clip-on foot for top hat rails, facilitating installation in control panels or protective enclosures.

Installation should be close to the system's earth start point or at the building entry/exit for optimal protection. It functions reliably across a wide temperature range from -25°C to 70°C, making it suitable for various industrial, commercial, and telecommunications applications.

The unit complies with ANSI/ESD S20.20:2014 standards and holds ATEX certification for hazardous area use, ensuring safety and compliance in critical environments. Applications include industrial automation, telecommunications networks, and process control systems where protection from transient surges is essential.
