Product Description

NH40 series isolation switch, suitable for AC 50Hz, AC rated voltage 690V and below, rated current up to 3150A. In the distribution equipment of industrial enterprises, it can be used for infrequent manual switching on and off the circuit and isolating the power supply, of which 125A~630A can be used for frequent switching on and off, and this series of switches cannot be used as a direct start of a single motor. Standard: GB/T 14048.3, IEC 60947-3.
The ambient air temperature is not higher than +40°C and not lower than -5°C.
The elevation of the installation site does not exceed 2000m, but the capacity can be reduced within 5000m, and the capacity is reduced by 5% for every 1000m higher than 2000m.
Humidity: When the maximum temperature is +40°C, the relative humidity of the air does not exceed 50%, and higher relative humidity can be allowed at lower temperatures, such as 90% at 20°C. Special measures should be taken for occasional condensation due to temperature changes.
The pollution level of the surrounding environment is Level 3.
The switch should be installed in a place where there is no significant shaking, shock vibration, and no rain or snow attack. At the same time, the installation place should be free from explosive dangerous media, and there is no gas and dust in the media that can corrode metal and destroy insulation.
