The Edco TCS-HW Series TVSS features a two-stage design that provides superior protection for sensitive equipment and for ANSI/IEE c62.41 Location Category A applications. Utilizing bipolar Silicon Avalanche Diode (SAD) technology, the Edco TCS-HW Series can be incorporated into larger power protection or used as point-of-application protection. Hardwired into a single 15- or 20-amp AC circuit, the Edco TCS-HW Series places protection at, or near, the critical load. The field-tested design ensures continuous protection in the most demanding environments with configuration available for 120 and 240VAC, single-phase applications.

  • Includes remote status indication with RJ11 jack.
  • Provides superior, non-degrading protection using bipolar SAD technology
  • Protects individual circuits
  • Provides independent secondary stage for maximum continued protection
  • Installs easily and uses a small amount of space
  • Withstands demanding environments with its rugged metal enclosure
