ATC Power Breaker Bypass Isolation Open/Closed Transition Automatic Transfer Switch - 1

CAT® ATC POWER BREAKER BYPASS ISOLATION OPEN / CLOSED TRANSITION AUTOMATIC TRANSFER SWITCH Cat® transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability and value in a compact package. A Bypass I solation 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. Breaker-based Bypass Isolation ATS are available from 200A to 5,000A. System test pushbutton Load shed from emergency Mimic diagram Safe manual operation under full load with permanently affixed operating handle Drawout capabilities on both ATS, bypass portions and power switching devices completely interchangeable between ATS and bypass units FEATURES • ATC-800 microprocessor-based controller • True RMS voltage and frequency sensing • Full 30-cycle short time withstand capability • 30-cycle, 85 kA short-time rating on power Circuit breaker • Multiple field programmable time delays • Switch position indication • Source availability indication • Source 1 and 2 auxiliary contacts • Programmable plant exerciser
