Transportation and Storage
* Avoid heavy weather attack and mechanical damage;
* Product storage Temperature: -40°C~120°C(-40°F~248°F);
* Product storage Humidity: T=40°C RH≤70%, T≤30°C RH≤80%, T≤20°C RH≤90%;
* Package storage Temperature: -40°C~80°C(-40°F~176°F);
* Package storage Humidity: RH≤90%, condensation free.

Operating conditions
* Fuses can perform regularly under the flowing conditions without corrections;
* If over the regular operating conditions but still in allowable operating area, fuses may need corrections and extra consult.
If the operating conditions is not matching the allowable area, please contact our company for more applicability tests and analysis;
* Regular current flow should ≤ 75% of recommended rated current;
* Operating temperature: -5°C~40°C(23°F~104°F);
* Allowable operating temperature:-40°C~125°C(-40°F~257°F);
* Temperature correction factors: when below -5°C(23°F), low overload (L.O.) pre-arcing time will slightly extend, rated current will slightly increase;
* If operating above 40°C(104°F),rated current need extra corrections, factors: -Kt①.
Note①: Kt value has already considered the safety current allowance under regular operating scenarios.
The picture see the following derating curve.

Vibration and Shock Resistance
* High frequency vibration resistance:≧20g;
* High frequency vibration resistance can satisfy track transportation/ motor vehicles;
* Intense vibration and shocking conditions need more tests.

Maintenance and Safety Instructions
* To use insulating board if needed for preventing shorting out;
* Maintain facilities regularly, Dusting/Antioxidation/etc.;
* Replacing fuses if damaging facilities;
* DO NOT change fuses while loading unless MUST.

Altitude
* Operating conditions: altitude≤2500m; Allowable operating conditions: altitude is from 2000m to 4500m;
* Altitude correction factors: high altitude will decrease the dielectric strength/ heat dissipation, and affect the pressure
force;

1. Fuses’ T-rise increase 0.1-0.5k from every 100m altitude increased;
2. Average environment temperature decreases 0.5k from every 100m altitude increased;
3. If operating in opening environment, ignore the altitude affect to rated current;
4. If operating in enclosed environment, and the environment temperature can still top 40°C(104°F),then rated current should be derated. Derating factors: 2%-5% from every 1000m altitude increase.

*Note: In same series, highest rated current refers to the maximum derating factors, lowest rated current refers to the minimum derating factors.
* Dielectric strength affects by high altitude;

1. Between 2000m-4500m, dielectric strength will decrease 12%-15% from every 1000m. quote GB/T16935.1, correcting from different dielectric gaps;
2. Fuses’ dielectric distance are normally much longer then GB/T16935.1, unless specific mini-sizes, ignore the dielectric
gaps;
3. Dielectric distance between fuses and other electronic structures or the ground differs from altitude heights.
