• New * 1 Year / 1,000 Hour Limited Warranty (Whichever comes first) * U.L. Listed * 60 HZ * 3 Pole * Amps: 100 * NEMA 3R Enclosure * 3 Phase * 277/480 Volt

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 Product Scope

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 Suitable for emergency and standby applications UL 1008 listed at 480 VAC CSA certified at 600 VAC IEC 947-6-1 listed at 480 VAC Open type, NEMA 1, 3R, 4, 4X and 12
