1. High breaking capacity: Rated breaking current is 31,5kA~50kA 2. Low power loss: Low temperature rise. When the fuses are used in whole-sealed insulated equipment, this feature is especially apparent. 3. Low electric arc voltage: In the breaking process, electric arc is much lower. 4. Low error in characteristics curve: The error in time-current characteristics curve is less than +10%. 5. Standardization norms: The ratings of the products comply with the standard R10, R20 series of International Electrotechnical Commission (IEC). 6. Equipped with Striker: The striker in parallel with the fused mass can act in several thousandths second after electric arc just appears, and give signals with enough energy, and make other electric appliances act, or afford interlock. The output energy of the fuse striker according with Germany Standard DIN is 3~5J. 7. Strong role of limiting current: Because of this, when selecting the conductor of protected component, you only need to design it according to the limited current value instead of full short-circuit current value. This can save conductor materials and other materials.
