CTX Series Automatic Transfer Switch
CTX Series Automatic Transfer Switch
Overview
Cat® CTX Series switches are built for residential and light commercial applications requiring the dependability and ease of operation found in a power contactor switch.
Voltage sensing and system control is performed via a state-of-the-art microcontroller located on the cabinet door.
