Conditions of use

Normal use conditions and parameter correction

The fuses work normally under the following normal conditions without any additional correction.

When it exceeds the normal using conditions, some parameters or consultation may need to be corrected if they are within the allowable using conditions. If it is beyond the scope of allowable using conditions, you should consult our company, and carry out the work adaptability evaluation and test of the conditions.

It is recommended that the current value of long-term current shall not be greater than 80% of the rated current. For over-temperature use, please refer to the temperature evaluation curve above.

Altitude: Altitude of the installation site not more than 2000m. If Altitude is more than 2000m, the rated voltage needs to reduce. 2000~4000m, when altitude rise 1000m, the rated voltage reduce 90%.

Ambient Air Temperature

Normal using conditions: -5°C ~ 60°C.

Permitted conditions: -55°C ~ 120°C.

FAQ

How to select the current of the fuse?

Generally, we will calculate our rated current fuse according to 1.5 times of the customer's actual operating current.
