For many years railroads have relied on nVent ERICO Rail Transient Barrier (RTB) products for protection against damaging voltage surges and transient events. Now nVent ERICO has launched RTBN, the next generation in rail data and signal surge protection. RTBN builds on the successful legacy of the nVent ERICO RTB products while adding features and functionality to meet the needs of modern railroads.

With a maximum surge rating of 40kA 8/20 (nominal surge rating is 20kA), RTBN continues to provide the industry-leading performance and reliability that end-users have come to expect. RTBN's DIN rail grounding connection eliminates the need for additional wires. Its new design is compact, with a latching surge module that minimizes issues caused by vibration and human error. Other added features include a thermal disconnect for safe failure, visual status indicators, and remote monitoring, all of which are now standard predictive maintenance functionalities.
