  • Integrated high voltage transient surge suppression with automatic transfer switch for alternate source of electricity
    Patent number: 6731484
    Abstract: An integrated transient voltage surge suppression system and automatic power transfer switch which includes a framework, an automatic transfer switch mounted to the framework, the automatic transfer switch being configured for electrical connection to a primary source of electrical power, a secondary source of electrical power, and a recipient electrical power load, the automatic transfer switch being configured to normally route primary electrical power from the primary source of electrical power to the recipient electrical power load, the automatic transfer switch being further configured to switch upon the occurrence of a predetermined switch condition such that the automatic power switch alternately routes secondary electrical power from the secondary source of electrical power to the recipient power load; and a transient voltage surge suppression device mounted to the framework and electrically positioned between the automatic transfer switch and the recipient electrical power load.
