The TRSS-485 (18mm) is a professional-grade AC Surge Protection Device optimized for reliable signal line shielding in standard industrial control panels. Featuring a robust 18mm wide enclosure, this device provides uncompromising protection for a pair of signal lines—including RS485 and DC power paths—against transient overvoltages. By utilizing a sophisticated circuit design, this AC Surge Protection Device ensures high-frequency data transmission with minimal interference, maintaining signal integrity across long-distance communication routes.

Advanced Two-Line Protection for Industrial Reliability Designed to meet stringent industrial requirements, this Surge Protection Device is capable of handling high discharge currents while maintaining an instantaneous response time. The unit features a 35mm DIN rail installation design which saves significant labor during setup and provides a stable voltage protection level for sensitive electronic components. Fully compliant with international standards IEC 61643-21 and EN 61643-21, this SPD is available in multiple protection voltages to match specific system requirements.
