ABB ATS - ZTE Series Standard


The ZTE Series automatic transfer switch (ATS) is ideal for use in today's 7x24 service centers, data warehouses and critical healthcare facilities. These mission critical sites demand more than just continuity of power, and the ZTE meets these challenges.

Poor power quality damages equipment and increases maintenance costs. Inherent power problems stay hidden when testing is ineffective or incomplete. Going beyond source switching and addressing the issues of complete power quality requires a whole new level of ATS capability. The ZTE Series ATS is ideal for use in this environment.

ZTE Series, Standard (Open) Transition

The GE Zenith ZTE standard (open) transition transfer switches go beyond just source switching. Integral metering and communications, high-level diagnostics and superlative flexibility make the ZTE a perfect solution for today?s mission critical source switching.

ZTED Series, Delayed Transition

The ZTED - Delayed Transition transfer switch offers the same features as the ZTE with the addition of an adjustable time delay in the centered "off" position. This delay allows motor loads to coast down and transformer field to decay; ensuring inductive loads are re-energized after transfer with only normal inrush starting currents.

ZTECT Series, Closed Transition

The ZTED - Delayed Transition transfer switch offers the same features as the ZTE with the addition of a high-speed drive system, which ensures the overlap of the normal and alternate sources is less than 100 milliseconds. When one source is not within normal limits, such as during a power outage, the ZTECT automatically operates in delayed transition mode.
