The Cat® CTG Series Automatic Transfer Switches (ATS) are pre-configured for applications requiring the dependability and ease of operation found in a full feature power contactor type transfer switch.CTG switches are equipped with the next generation MX150 microprocessor panel, which controls the operation and displays the status of the transfer switch’s position, timers and available sources. As an embedded digital controller, the MX150 offers high reliability and ease of unattended operation across a range of applications.
Benefits
