We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap rt18-125 solar fuse link ac 1140v from our factory.
Product Introduction
The Hongman RT18 series fuses are high-performance cylindrical fuses fully compliant with international standards IEC60269-2 and GB/T13539.2. Covering a complete current range from 0.5A to 125A, these industrial ceramic fuses offer a maximum rated AC voltage of up to 1140V and a rated breaking capacity as high as 80kA, providing reliable overload and short-circuit protection for low-voltage industrial power distribution, motor control, and new energy power systems.
1.Ultra-wide current coverage from 0.5A miniature load to 125A heavy industrial circuit, one series meets all low-voltage protection demands.
2.99% high-purity silica sand arc extinguishing medium, reliable arc suppression without flashover or explosion under 80kA short-circuit impact.
3.Pure red copper conductive structure, low temperature rise, stable operation under long-term full load, strong anti-aging performance.
