Phoenix Contact AC SYSTEMTRAB – UL 1449 3rd Edition

Remote sites are facilities or structures that contain electrical or electronic processes and are located in hard-to-reach areas. The high cost of service and the long meantime to repair require higher level of surge protection. Specifically, applications in these facilities must be able to handle multiple high energy surge events, such as lightning, without compromising the surge protection.

The AC SYSTEMTRAB can handle multiple high-energy surge events, such as lightning, without compromising its surge protection. Even if it is damaged, your critical equipment will still be protected from future surges until a repair can be performed. This dual stage device provides notification when the protection level reaches 50 percent. All models are available in the following voltages:

  • 120/240 Single/split phase
  • 480/277 Wye
  • 480 Delta
