Cat® transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability and value in a compact package. A Bypass Isolation Automatic Transfer Switch (ATS) provides fully functioning transfer in applications where emergency power to critical loads must be maintained at all times with no interruption. This type of design allows for inspection, maintenance or replacement of the power switching mechanisms with no interruption in electrical service. Contactor -based Bypass Isolation ATS are available from 100A to 1200A. Benefits ATC-300+ or ATC-900 microprocessor-based controller Maintains fully automatic capability while in bypass mode (optional) All Controls relays and industrial grade relays Lugs are 90°C rated and all control wire is #16 AWG, type XLPE with a 125°C temperature rating Features At A Glance Product Features ATC-300+ or ATC-800 microprocessor-based controller True RMS voltage and frequency sensing Maintains fully automatic capability while in bypass mode (optional) Single motion rack-out with the door closed Multiple field programmable time delays Switch position indication Source availability indication Source 1 and 2 auxiliary contacts Programmable plant exerciser System test pushbutton Load shed from emergency Mimic diagram Ability to test power switching isolated components
