1H20E Series AC/DC (EV) fuse
1. Purpose and use
This series of fuses are applicable to rated DC voltage (125V / 150V), AC 300V, rated current 50A-400A and high sectioning capacity (50kA AC / 20kA DC). It is widely used in semiconductor protection, mobile forklift, electric elevator, charger, power supply, on-board battery, on-board circuit system and inverter integrated protection. At the same time, it has the characteristics of strong current limiting capacity, large breaking capacity and fast short-circuit breaking speed. Can withstand temperature shock, mechanical shock, current shock, chemical load, etc. Performance reference UL248-13.
2. Normal working conditions
Normal operating conditions of ambient air temperature: -5 ℃ ~ 40 ℃; allowable operating conditions: -40 ℃ ~ +125 ℃;
3. Use category
Full range fast fuse (aR)
4. Structural characteristics
The melting pipe of the product is made of high-temperature resistant ceramic materials, with high flame retardant performance and strong hardness.
The melt is sealed in the melting tube with a variable cross-section melt made of 99.99% pure silver. The melting tube is filled with chemically treated high-purity quartz sand and specially treated chemical materials as arc extinguishing medium. Silver plating on the contact surface ensures reliable electrical performance and reduces temperature rise and power consumption; Both ends of the melt are firmly connected with the contact through spot welding, which improves the safety and reliability of breaking short-circuit fault current.
