The I2R 75K series of modular DIN Rail AC Surge Protection Devices (SPD) are ideal for industrial communications, public safety, security as well as automation and control applications where UL Type 1 and Type 2 requirements are needed. The I2R 75K series offers configurations for all standard electrical service applications up to 690 Vac, including single phase, split phase, delta and three-phase WYE and are UL 1449 4th Edition approved.

Network safety and reliability are built into the I2R 75K series. Engineered using a safefail self-protection design, the I2R SPD couples a high short circuit rating with thermally protected MOV, which eliminates the need for additional back up fusing.

Through superior design, each I2R provides a robust 75 kA surge capacity that protects critical equipment against both high energy transients and long term exposure to harsh electrical environments.

• Safe-fail, self-protected design
