I2R T-series Addresses Expanding Automation, Security, Utility and Smart Grid Networks Worldwide

Transtector Systems, an industry-leading provider of end-to-end power and signal integrity solutions, today launched a comprehensive line of modular DIN rail AC surge protection devices (SPDs) for international industrial applications, focusing on the growing need for reliable protection in global security, utility, automation and control, public safety, smart grid and other critical markets.

Versatility, reliability and international compatibility are the keys to the I2R T-series line. Transtector offers configurations for Class I induced lightning protection ranging from 120 Vac to 690 Vac, along with Class I+II protection (induced and conducted lightning) in an array of 230 Vac options.

Industrial network applications are continuing to grow and diversify worldwide, and the mission-critical nature of these networks demands reliable surge protection,” said Dan Rebeck, Product Line Manager for Transtector. “With the I2R T-series, we’re providing three families of solutions for a range of environments and requirements, and each SPD features engineered-in reliability to ensure long-term performance even in the most challenging environments.”

Each I2R T-series SPD provides a robust surge capacity that protects critical equipment against both high energy transients and long-term exposure to harsh electrical environments.

Key I2R T-series features include:

  • A broad range of configurations designed to protect TNS, TNC and TT networks
  • Tiered protection levels available—ratings and capacities to fit the specific application
  • Options include SPDs rated for Class I or Class I+II lightning protection
  • Both remote and clear visual status indicators
