ZTG-General Purpose


The Zenith ZTG Series of transfer switches are built for general purpose commercial and industrial applications requiring the dependability and ease of operation found in a power contactor switch. The ZTG series uses the MX150 microprocessor control system, which includes features specified on a general purpose commercial and industrial applications. It also provides an intuitive user interface, communications capability and self diagnostics. The ZTG Series is available in a full range of ampere, voltage and pole configurations, along with many commonly requested options and features.

Configurations

ZTG – Standard (Open) Transition
The Zenith ZTG transfer switch is used in general and mixed load applications .
ZTGD – Delayed Transition
The Zenith ZTGD transfer switch is used to transfer of motor loads, and transformers.

Features & Benefits

  • Close differential under-voltage sensing of the normal source
  • Voltage and frequency sensing of the emergency source
  • Test switch (fast test/load/no load) to simulate normal source failure – automatically bypassed should the emergency source fail
  • Double throw, interlocked operation
  • Electrically operated, mechanically held by a simple, over-center mechanism
  • Segmented silver tungsten alloy contacts with separate arcing contacts on 600 amps and above
  • Arc quenching grids, enclosed arc chambers and wide contact air gap for superior source-to-source isolation on all units
  • Control circuit disconnect plug and drive inhibit switch for safe maintenance
  • Components accessible for inspection and maintenance without removal of the switch or the power conductors
  • Mechanical indicator and contact chamber cover designed for inspection, safety and position designation


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.

Configurations

ZTGSE – Standard (Open) Transition Service Entrance Rated
The Zenith ZTGSE transfer switch is used in general and mixed load applications where an integrated service entrance breaker is required.
ZTGDSE – Delayed Transition Service Entrance Rated
The Zenith ZTGDSE transfer switch is used to transfer of large motor loads, transformers, uninterruptible power supplies (UPS) systems where an integrated service entrance breaker is required.

Features & Benefits

  • Double throw, mechanically interlocked contactor mechanism.
  • Electrically operated, mechanically held.
  • Additional options include battery charger, GFP, shunt trip selector, power monitor and SPD surge protection.
