ZTX Series - Standard(Open) Transition

ZTX Series - Standard (Open) Transition

The Zenith ZTX Series of transfer switches is built for residential and light commercial critical/non-life safety applications requiring the dependability and ease of operation found in a power contactor switch. The ZTX transfer switches are designed for standby applications, and incorporate a double-throw, mechanically interlocked contactor mechanism.

 

 

The ZTX transfer switches are equipped with the MX60 Control Panel.
