TGLD series automatic transfer switching equipment is suitable for AC 50Hz three-phase four-wire dualcircuit power supply grid with rated working voltage AC400V and rated current up to 1600A to disconnect the load circuit from one power supply and connect it to the other power supply.
This transfer switching equipment has automatic action and optional manual operating functions.
Working environment conditions:
1.1 Ambient air temperature: The upper limit of ambient air temperature is +40℃, and the lower limit is -5℃; the mean temperature within 24h does not exceed +35℃;
1.2 Altitude: The altitude at the installation site does not exceed 2,000 meters;
1.3 Atmospheric conditions: The relative humidity of atmospheric air does not exceed 50% at the highest ambient temperature +40℃, and a lower relative humidity is allowed at a lower temperature, such as up to 90% at +20℃. Special measures are taken for condensation occurred occasionally due to temperature changes;
1.4 Pollution degree: Level 3.
