Product Benefits

1. Amps:1~32A; Volts: 1000VDC; Breaking Capacity:20kA
2. Compact design,Low power loss,Excellent DC performance.
3. Low arc voltage and low energy let-through(I2t).
4. Product storage temperature: -40°C~120°C. At 40°CC, the relative humidity is not more than 70%, below 30°C, not more than 80%, below 20°C, not more than 90%
5. Packaging and storage temperature: -40°C~80°C. The relative humidity is not more than 90%, and there is no condensation

Vibration and Shock Resistance

1. It has good resistance to vibration and impact, and can withstand more than 20g Comply with the IT application environment of rail transit and the use of general motor vehicles.
2. In the application environment with strong vibration, the corresponding test can be negotiated, which generally needs a long period.

Altitude

1.2000 – 4500m
2.Higher altitude mainly leads to insulation deterioration, heat dissipation condition deterioration and air pressure change.
A) The temperature rise of the fuse increases by 0.1-0.5k every 100m above sea level.
B) For every 100m increase in altitude, the average ambient temperature decreases by about 0.5K.
C) In open environment, the influence of altitude on rated current can be ignored.
D) When used in a closed environment, if the air temperature or box temperature does not decrease with the increase of altitude and still reaches more than 40°C,  the rated current needs to be reduced. The rated current shall be reduced by 2%-5% for every 1000m increase in altitude.
3.Effect of altitude on air insulation strength (breakdown strength)
A) Within 2000-4500m, the insulation strength decreases by 12-15% for every 1000m increase in altitude
B) the insulation gap between the fuse and other live structures and to the ground shall be considered by the user.
