JRN600V Series PPTC Resettable Fuse | 600V High-Voltage Polyfuse for Industrial & New Energy Circuit Protection
The JRN600V Series provides resettable overcurrent protection for high-voltage circuits up to 600V AC/DC, using PPTC (Polymeric Positive Temperature Coefficient) technology. During fault events such as overcurrent or short circuit, the device rapidly increases in resistance, effectively limiting current flow and protecting the load. After cooling, it automatically resets and resumes normal operation. With high voltage withstand, long cycle life, and high reliability, it's ideal for AC mains protection, industrial power modules, energy storage systems, and appliance control boards.
