CTE 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.
MX Control Panel
- CTX switches are equipped with the MX-60 control panel as standard.
- Undervoltage sensing (90% pickup/80% dropout of the utility source
- Voltage and frequency sensing of the generator source (90% voltage/95% frequency pickup)
- Time Delay Engine Start – 5 seconds (P)
This microprocessor control includes:
