ZTG Series – Standard (Open) or Delayed Transition
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 for the transfer of large motor or inductive loads.
- 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
