1. Introduction
This 5H30L Series Fast Fuses are suitable for rated DC voltage up to 500V (450V), In the line with rated current up to 250A, the breaking capacity is 50kA, which is the comprehensive protection of on-board battery, on-board line system and inverter. At the same time, it has the characteristics of strong current limiting capacity, high breaking capacity, fast short-circuit breaking speed, and it can withstand temperature shock, mechanical vibration shock, current shock, chemical load, etc.
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
4. Structural characteristics
The melting tube of the product is made of high-temperature resistant ceramic material, 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. The contact surface is silver plated to ensure reliable electrical performance, greatly reducing temperature rise and power consumption; Both ends of the melt are firmly connected with the contact by spot welding, which greatly enhances the safety and reliability of breaking short circuit fault current.
This series of High Speed Fuses conforms to ISO 8820 and Jaso D622 and GB / T31465.Applicable standards for environmental reliability: GB/T31465.6, ISO 8820-8, JASO D622, UL248-20.
