Designed for standard applications, the ZTG Series builds on ZTS technology while providing a pre-engineered project solution.
The series uses the MX150 microprocessor control system, which includes as standard many of the most common features specified on a transfer switch. It also provides an intuitive user interface, communications capability and self diagnostics.
The ZTG is available in a full range of ampere, voltage and pole configurations, along with many commonly requested options and enclosure types.
Features and 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
Ratings 40 to 3000 amperes
2, 3 or 4 poles
Double throw, mechanically interlocked contactor mechanism
Available in ZTG (standard) or ZTGD (delayed transition) models
