✓Compact size, equipped with PV2-32 (L) fuse type isolator, rail type installation, which is easy to install.
✓Features the advantage of excellent fusing characteristics and low power loss.
Normal Installation Conditions
Ambient temperature: -25°C ~ +60°C. This refers to the air temperature directly surrounding the fuse link, which should not be confused with the room temperature. In practical applications, the temperature of the fuse link can be high as it is enclosed in a support/base and power distribution control cabinet.
Atmospheric conditions: Relative humidity should not exceed 50% at a maximum temperature of +60°C. Higher relative humidity is allowed at lower temperatures. The monthly average minimum temperature of the wettest month shall not exceed -25°C, with a maximum relative humidity of 90%. Preventive measures must be taken against condensation.
Pollution level: 3 | Installation category: Class Ⅲ
Installation place: The fuse shall be free from significant shaking and shock vibration.
When ordering fuses, please indicate the model, specification, quantity, as well as the rated voltage and current grade of the corresponding fuses. For fuses with special specifications or unique current levels, please consult for customized solutions.
