Checking for live stock

The WJ Furse 7TCA085400R0191 ESP RS485 is a specialised surge protection device engineered to safeguard data and signal lines. It is specifically designed for RS485 signalling systems and Fieldbus applications like Profibus DP. This surge suppressor unit provides full-mode protection against transient overvoltages caused by lightning or electrical switching. With a slim DIN rail mountable design, it fits easily into compact control panels. It ensures continuous equipment operation by limiting let-through voltage to safe levels during surge events.

Main Reasons to Use This Product

This WJ Furse 7TCA085400R0191 ESP RS485 surge suppressor prevents costly downtime by protecting sensitive communication interfaces from voltage spikes. Its low in-line resistance ensures that signal strength remains unaffected during normal operation.
