Product Introduction

PZ-type distribution box (distribution board) for three-phase AC 50Hz, rated voltage 220V / 380V, the main bus rated current 100A and below the three-phase four-wire power system, as to receive power and distribution of energy use. Widely used in industrial and mining enterprises and civil construction of the distribution, lighting, measurement and other purposes. Products with good security, electrical program flexibility, the combination of convenience, series, practical and strong, novel structure, high degree of protection features.

 

Model Description:

PZ

└────────── Distribution box

 

Conditions of Use

The surrounding air temperature is not higher than +40 ℃; not less than -5 ℃; and 24 hours, the average temperature is not higher than +35 ℃.

Ambient air relative humidity at a maximum temperature of +40 ℃ not more than 50%, at lower temperatures allow a greater relative humidity, such as +20 ℃ 90%, but should be taken into account as a result of temperature changes may Occasionally produce moderate condensation.

Indoor use, the use of the altitude of not more than 2000m.

Should be installed in the absence of severe vibration and shock and not enough to make electrical components subject to corrosion of the place.
