WJ Furse Twisted Pair Surge Suppressor Unit 58V Maximum Voltage 20 kA Maximum Surge Current ESP D/TN 7TCA085400R0109 ESP 50D

WJ Furse 7TCA085400R0109 ESP 50D is a high-performance twisted pair surge suppressor unit engineered to protect sensitive electronic equipment in industrial, laboratory, and communication environments. It features a maximum voltage rating of 58V and can handle surge currents up to 20 kA, delivering effective and reliable suppression of transient surges.

The device is designed for installation on DIN rails and encased in a robust, flame retardant ABS housing. This surge protection unit provides full mode protection with very low let-through voltage in accordance with BS EN 62305, allowing equipment to continue operating safely under transient surge conditions including partial lightning currents.

Its colour-coded terminals and integral earthing plate facilitate easy installation and enhance grounding effectiveness. The suppressor operates efficiently within a temperature range of -25°C to 70°C, making it suitable for various environmental conditions.

Typical applications include protection of twisted-pair lines found in process control equipment, modems, and communications interfaces. Recommended installation is close to the earth start point of the system, such as within control panels or at entry/exit points of buildings. It may be housed in dedicated or existing enclosures for ease of maintenance and system integration.

Designed specifically for twisted-pair line surge protection. Maximum voltage rating: 58V and surge current capacity: 20 kA. DIN rail mountable with options for base or side mounting and clip-on on top hat rails. Flame retardant ABS housing provides mechanical protection and safety.

Integral earthing plate and substantial earth stud for enhanced grounding connection. Low inline resistance ensures minimal interference with signal integrity. Temperature operation range from -25°C to +70°C suitable for various environments.

Provides repeated protection in lightning intense conditions. Meets ANSI/ESD S20.20:2014 and ATEX hazardous area certification standards.

This surge suppressor is an essential component in industrial and commercial electrical systems to safeguard communication and control equipment from damaging transient voltages and surges. It is widely used in manufacturing, automation, HVAC, water treatment, and telecommunications sectors.
