  • TSi 40kA is available in 1, 2, 3, or 4 Pole configurations
  • Designed for 120V, 240V, 277V and 480V applications
  • Standard Warranty, Two (2) Years

It is important to recognize that every wire connected to your equipment, even though it may not be in use, provides a path for harmful surges and transients to reach your sensitive electronic equipment. THOR SYSTEMS offers a wide range of high-quality surge protection systems and power quality site-specific solutions. All of our products are designed to improve efficiency, eliminate downtime, and protect missioncritical electronic equipment. Our solutions are installed in critical locations, i.e. protecting electrical service entrances and distribution systems, as well as data and telecommunications systems.
