Conditions of use
Normal use conditions and parameter correction
The fuse works under the normal use conditions described below and does not require additional modification.
When it exceeds the normal use conditions, if it is within the allowable use conditions, it may be necessary to modify some parameters or consult. If it exceeds the range of allowable use conditions, you should consult our company, and conduct work suitability assessment and testing of the conditions.
It is recommended that the current value of long-term flow is not more than 80% of the rated current. Please refer to the above-mentioned temperature evaluation curve for over-temperature use.
Altitude: The altitude of the installation site does not exceed 2000m. If the altitude exceeds 2000m, the rated voltage needs to be reduced. 2000~4000m, the rated voltage is reduced by 90% for every 1000m increase.
Ambient air temperature
Normal use conditions: -5℃～60℃.
Allowable use conditions: -55℃～120℃.
