Normal use conditions and parameter correction

• The fuses work normally under the following normal conditions and no any additional correction required.
• 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.

Ambient Air Temperature

Normal using conditions: -5°C ~ 40°C.

Permitted conditions: -40℃～85℃.

Parameter correction for ambient air temperature changes: working below -5°C, the pre-arc time of the fuse's low overload current is slightly extended, and the rated current is slightly increased. But unless above -5℃ is not in the working range, generally do not consider increasing the rated current of the fuse. The fuse works above 40℃, the rated current needs additional correction, and the correction factor is -Kt.

Note 1: The value of Kt has taken into account the influence of the rated current safety margin of the fuse under normal operating conditions.

Note 2: The ambient air temperature needs to last for more than 1 to 2 hours before it has a significant impact.
