EV Fuses For New Energy Vehicles
The Prosemi EV (Electric Vehicle) fuses are made of high strength ceramic tube and high purity melt, with unique arc extinction filling technology which is Prosemi's patent technology . The EV fuses are elaborately designed according to the actual driving status of EVs, with adherence to auto industry standards (JASO, D622/ISO8820). With high vibration durability, pefect transient current intermittent tolerance, eminent thermal shock resistance and favorable flame retardant ability, the Prosemi fuses will provide youprotection whether the vehicle is traveling on a flat road or under a variety of harsh conditions.

Conditions for operation in service
Where the following conditions apply, fuses complying with this standard are deemed capable of operating satisfactorily without further qualification.
If the operating conditions exceed the following requirements, please contact manufacturer.
- Normal temperature: -5℃ to 40℃;
- The altitude of the site of installation of the fuses 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.
Vibration
Meet JASO D622:2006 Section 6.3.3 Vibration durability test requirement, can be use on Electrical Vehicle application;
Temperature Derating Curve
Operating Temperature: -40°C to +125°C, with proper rerating factor applied.
