Product Description and Specifications

Series: ZTG
Applications: General Purpose
Amperage: 40 – 3,000
Poles: 2, 3 or 4
Voltage: 120 – 600V

The Zenith ZTGSE and ZTGDSE Service Entrance Rated automatic transfer switches integrate a utility main disconnect, optional surge protective device (SPD) and power monitoring into one compact coordinated package.

The ZTGSE series provides greater protection to critical loads against utility power outages and transient voltage disturbances. This delivers more peace of mind to facility managers and business owners in a wide range of industries such as water/wastewater reclamation, retail, agricultural, light manufacturing, wireless communications and other service businesses.

ZTGSE switches are equipped with GE’s MX150 microprocessor panel, which controls the operation and indicates the status of the transfer switch’s position and available sources. As an embedded digital controller, the MX150 utilizes an easy to read LCD display with statistical event recording and basic metering as standard features.
