Overview

Cat® transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability and value in a compact package. The open transition power case switch-based Automatic Transfer Switch (ATS) will provide fully functioning transfer in applications where a momentary loss of power is acceptable on retransfer from emergency to normal power supply. The Cat power case switch-based ATS also permits periodic testing of the emergency source without interrupting power to the loads and are available from 200 to 5000.

Benefits

microprocessor-based controller and Power Breaker

Fastest switching times available (<3 cycles) Full 60-cycle short time withstand capability

controls relays and industrial grade relays

Lugs are 90ï¿½ rated and all control wire is #16 AWG, type XLPE with a 125ï¿½ temperature rating.

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
