Ambient air temperature The upper limit for the ambient air temperature is +40°C, lower limit -5°C, and the mean value of the temperature is not greater than ＋35°C within 24 hours; 3.2 AltitudeAltitude: not higher than 2,000m for the installation site. 3.3 Atmospheric conditions:
When the ambient air temperature is +40°C, the relative humidity of the air shall not be higher than 50%, a higher relative humidity is allowed at a lower temperature, e.g. 90% at +20°C, and special measures shall be taken for the condensation occasionally produced due to temperature changes. 3.4 Class of pollution: Class of pollution: 3

Technical data5. Characteristics and functionsThe NZ7 series automatic transfer switching equipment (hereinafter referred to as automatic transfer switch) is the CB class product of a new generation combined with the advanced digital electronic control technique.
The product features compactness, energy conservation, convenient installation, reliable dual-interlock protection, etc., and is advanced and complete in terms of function.
5.1 CompactnessThe transfer function is achieved via using the forward and backward rotation of the only one motor which allows for reducing the product’s height and room for its installation.5.2 Energy savingThe driving mechanism works in the mode of motor drive with less power consumption and noise.
Dual-interlock protection The mechanical-electrical interlock duplex protection is used to prevent two power sources from being connected simultaneously to the load, wherein the electrical interlock works in the breaker contact position mode for directly indicating the automatic transfer switch to perform the genuine electrical interlock so that the automatic transfer does not take place automatically in such cases as contact fusion welding, breaker handle damage, and circuit fault breaker tripping.
