Company Profile

HIGH SPEED FUSES HV 160V 1500Vdc

Product Description:

With an IR rating of 120kA@1500Vdc, this high voltage backup fuse is able to handle high levels of electrical energy, ensuring that your electrical equipment and infrastructure are protected from damage or failure due to overcurrents.

Our high voltage expulsion fuse is designed to conform to the GB13539/IEC60269 standards and approvals, ensuring that it meets the highest quality and safety standards. You can trust that this fuse will perform reliably and consistently under high voltage conditions.

One of the key features of this high voltage current limiting fuse is its fast arcing time of less than 5ms. This means that in the event of an overcurrent, the fuse will quickly and efficiently isolate the fault to prevent damage to your electrical system.

Investing in our high voltage current limiting fuse is a smart choice for any high voltage electrical installation. With its reliable performance, high IR rating, and fast arcing time, you can trust that your electrical system is protected from overcurrents.

Features & Benefits:

It is used for short circuit protection of energy storage device, UPS center, charging system, inverter, charging pile. This series of fuses are cured by the

world’s most advanced curing technology, which effectively improves the vibration resistance and high current breaking ability.

Transportation and Storage

Avoid heavy weather attack and mechanical damage;

Product storage Temperature: -40° C~120° C(-40° F~248° F)；

Product storage Humidity: T=40°C RH≤70%, T≤30°C RH≤80%, T≤20°C RH≤90%

Package storage Temperature: -40° C~80° C(-40° F~176° F);

Package storage Humidity: RH≤90%, condensation free.

Operating Conditions

 Fuses can perform regularly under the flowing conditions without corrections;

If over the regular operating conditions but still in allowable operating area, fuses may need corrections and extra consult. If the operating conditions is not

matching the allowable area, please contact our company for more applicability tests and analysis;

 Regular current flow should ≤ 75% of recommended rated current;

 Operating temperature: -5° C~40° C(23° F~104° F);

 Allowable operating temperature:-40° C~125° C(-40° F~257° F);

 Temperature correction factors: when below -5° C(23° F), low overload (L.O.) pre-arcing time will slightly extend, rated current will slightly increase;

 If operating above 40° C(104° F),rated current need extra corrections, factors: -Kt①.

*Note①: Kt value has already considered the safety current allowance under regular operating scenarios.

Altitude

 Operating conditions: altitude≤2500m; Allowable operating conditions: altitude is from 2000m to 4500m;

 Altitude correction factors: high altitude will decrease the dielectric strength/ heat dissipation, and affect the pressure force.

a) Fuses’ T-rise increase 0.1-0.5k from every 100m altitude increased;

b) Average environment temperature decreases 0.5k from every 100m altitude increased;

c) If operating in opening environment, ignore the altitude affect to rated current;

d) If operating in enclosed environment, and the environment temperature can still top 40° C(104° F),then rated current should be derated. Derating

factors: 2%-5% from every 1000m altitude increase.

*Note: In same series, highest rated current refers to the maximum derating factors, lowest rated current refers to the minimum derating factors.

 Dielectric strength affects by high altitude;

a) Between 2000m-4500m, dielectric strength will decrease 12%-15% from every 1000m. quote GB/T16935.1, correcting from different dielectric gaps;

b) Fuses’ dielectric distance are normally much longer then GB/T16935.1, unless specific mini-sizes, ignore the dielectric gaps;

c) Dielectric distance between fuses and other electronic structures or the ground differs from altitude heights.

Vibration and Shock Resistance

 High frequency vibration resistance:≧20g;

 High frequency vibration resistance can satisfy track transportation/ motor vehicles;

 Intense vibration and shocking conditions need more tests.

Maintenance and Safety Instructions

 To use insulating board if needed for preventing shorting out;

 Maintain facilities regularly, Dusting/Antioxidation/etc.;

 Replacing fuses if damaging facilities;

 DO NOT change fuses while loading unless MUST.
