JRN250V Series PPTC Resettable Fuse | 250V High-Voltage Polyfuse for Resettable Overcurrent Protection
The JRN250V Series is a PPTC (Polymeric Positive Temperature Coefficient) resettable fuse designed for high-voltage systems up to 250V AC or DC. When overcurrent occurs, the device quickly heats up and switches to a high-resistance state, limiting current flow and protecting the circuit. Once the fault is cleared and the device cools, it resets automatically, allowing repeated use. This series is ideal for power adapters, EV chargers, smart home modules, AC mains interfaces, and LED drivers.
