System Description
The Series TVSS has been designed to respond to the many applications where the cause or threat can be attributed to a specific source or piece of equipment. When that occurs and the cause is surge, then a surge suppression device (TVSS) may be all that you need. It is very cost effective and can be installed to protect a specific load or one specific piece of equipment. PS&C offers a UL 1449 Second Edition listed TVSS product line. The range of this line starts at the Service Entrance/Main Distribution panel up to 320kA per phase and goes down to the Secondary Distribution/At the Load up to 80kA per phase. With MOV-based technology, these systems provide many options to get maximum value for you power protection investment.
