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 does not exceed 2 000 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 conditions other than above, please contact manufacturer.
Vibration
Meet JASO D622:2006 Section 6.3.3 Vibration durability test requirement; suitable for EV applications.
