Overview

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.

All controls relays and industrial grade relays

Lugs are 90� rated and all control wire is #16 AWG, type XLPE with a 125� temperature rating.

ATC-900 microprocessor-based controller and Power Breaker

Full 30-cycle short time withstand capability 30-cycle, 85 kA short-time rating on power circuit breaker

Durable Durable powder-coated steel NEMA 1, 3R or 12 enclosures with three door hinges.

The hinges have removable hinge pins to facilitate door removal and are supplied with pad-lockable latches.
