小型熔断器的发展

工业熔断器
Industrial Fuses

10x38 陶瓷管状也应用于大 电流电子电路中 10x38 ceramic tube fuses is also suitable to high current circuit. 工业熔断器有美规和欧规的 许多不同系列 Industrial fuses also have a lot of American standard and Europe standard series.

小型熔断器的认证
Miniature Fuses’ Certification
安全认证也分美规和欧规两大体系. Safety certification is also classed into American and Europe standard two series. UL/CSA列名和UL/CSA认可 UL.CSA Listed and UL/CSA Recognized VDE(德)/SEMKO(瑞)/BSI(英)/FEMKO(芬)… IEC standard: VDE / SEMKO / BSI / FEMKO…… CCC属欧规体系, 可以利用CB来转换其他认证. CCC certification is belong to Europe system Rransferred to other certifications by CB certificate
