RS17 20A 500V Cylindrical Fast-Acting Fuse | 22*58mm | CCC Certified

This RS17 20A 500V cylindrical fast-acting fuse is manufactured by ZHENGRONG Fuse Co., Ltd., featuring a compact 22x58mm size and CCC certification. Designed as a high-breaking-capacity, fast-acting protective component, it is widely used in AC 50Hz circuits to provide reliable overload and short circuit protection for electrical equipment.

The fuse adopts a ceramic tube and metal end cap structure, with built-in quartz sand filler to quickly extinguish arcs, ensuring safe circuit disconnection under fault conditions. It is compatible with standard RT18 fuse bases, making installation and replacement convenient. RS17 is interchangeable with RO17 models, making it one of the most commonly used overcurrent protection devices in industrial and new energy fields.
