Influence of low temperature environment on the use of fire distribution box

It is also possible to use fire distribution box in low temperature environment, but protective measures need to be taken. The upper limit of ambient air temperature around the distribution box shall not exceed 40 ℃, the average ambient air temperature within 24 hours shall not exceed 35 ℃, and the lower limit of ambient air temperature shall not be lower than - 5 ℃ or - 25 ℃. In summer, the operation of the distribution box will produce a lot of heat. In midsummer, the temperature of the box will reach 60 ℃. However, the temperature of the electrical components in the distribution box is much higher than the specified temperature.

In the selection, there is a problem in the selection of components in the consumer distribution box, which will cause unnecessary failure and affect the use of the distribution box.
