Requirements

Ambient air temperature a. -5℃ ~ 40℃, b. The average value of ambient air temperature in 24 hours does not exceed 35℃.

The altitude of the installation site does not exceed 2000m.

Atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is 40°C. It can have higher relative humidity at lower temperatures (for example: at 20°C, the relative humidity can reach 90%). The wettest month The monthly average maximum relative humidity does not exceed 90%, and the monthly average minimum temperature of the month does not exceed 25°C, and condensation on the product surface due to temperature changes is taken into account.

Voltage: The maximum value of the system voltage shall not exceed 110% of the rated voltage of the fuse. For DC voltage rectified from AC, the change caused by the pulsation shall not be greater than 5% or not less than 9% of the average value of 110% of the rated voltage.

Current: The current carried by the fuse is within the range of rated current and breaking current.

Frequency: Rated frequency is 45-62Hz.

Installation conditions:

Fuses can be installed vertically, horizontally or at an angle.

There is no significant vibration or impact in the workplace.

The air in the installation location should be clean.

Note: For the relevant requirements for fuses used under special working conditions, the user should contact our company for negotiation.
