1. Introduction
This 10H30L Series DC automobile fuses are suitable for lines with rated DC voltage below 1000V, rated current of 100A-200A and breaking capacity of 50kA. They are widely used in chargers. Comprehensive protection of charging pile, on-board battery, on-board circuit system and inverter. This series of HVDC Fuses conform to ISO 8820, JASO D622 and GB / T31465 standards. Applicable standards of environmental reliability: GB / T31465.6, ISO 8820-8, JASO D622, UL248-20.

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（gR)

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.
Fast DC fuse has the characteristics of strong current limiting capacity, large breaking capacity and fast short-circuit breaking speed. It can withstand temperature shock, mechanical vibration shock, current shock, chemical load, etc.

5. Agreed current and agreed time

Note: the agreed current and agreed time required by the customer can be negotiated with our company.
The characteristics of fuse will vary according to the use environment and surrounding design requirements. The performance characteristics are obtained according to the rated constant temperature of 25 ℃
