Zenith ZTS-D Delayed Transition Series ATS
When large motors, uninterruptible power supply (UPS) systems and/or transformers make up the bulk of the load, delayed transition transfer switches offer ideal protection.
The GE Zenith ZTS-D Series provides an adjustable time delay in the centered “off” position. This delay allows motors to coast down and transformers to decay, meaning inductive loads may be re-energized after transfer with only normal inrush starting currents.
These switches, which are strongly recommended by major UPS manufacturers, are ideal for pumping stations, sewage treatment plants, hospital X-ray equipment or whererever the load makes a delay desirable.
The ZTS-D Series incorporates all the important features of the standard ZTS Series in a unique design that includes specific operational properties. The performance, operating capabilities, ratings, and UL listings all withstand current values and available options are identical to those of the ZTS Series.
