Conditions for operation in service
Where the following conditions apply, fuses complying with this standard are deemed capable of operating satisfactorily without further qualification.
- Normal temperature: -5℃ to 40℃;
- The altitude of the site of installation of the fuses does not exceed 2000 m above sea level;
- The air is clean and its relative humidity does not exceed 50% at the maximum temperature of 40℃;
- Higher relative humidities are permitted at lower temperatures, e.g. 90 % at 20℃;
- Under these conditions, moderate condensation may occasionally occur due to variation in temperature.
For operation condition other than above, please contact manufacturer.
Vibration
Meet UL248-20 Section 8.6.2.3 Vibration Test C requirement, can be use on Electrical Vehicle application.
Temperature Rerating Curve
Operating Temperature: -40°C to +125°C, with proper rerating factor applied
