ATC Contactor-Based Bypass Isolation Transfer Switch - 1

AUTOMATIC TRANSFER SWITCH CAT® ATC CONTACTOR-BASED BYPASS ISOLATION AUTOMATIC TRANSFER SWITCH Ca t® 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 wit h no interruption. This type of design allows for ins pection, maintenance or replacement of the power sw itching mechanisms with no interruption in electrical service. Contactor -based Bypass Isolation ATS are available from 100A to 1200A. • 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 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
