ATC POWER BREAKER BYPASS ISOLATION OPEN/CLOSED TRANSITION AUTOMATIC TRANSFER SWITCH

Back to the list

OVERVIEW SPECIFICATIONS EQUIPMENT

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. Breaker based Bypass isolation ATS are available from 200A to 5,000A.
