The Protectron RLD120PO25X is a PTC (Positive Temperature Coefficient) resettable fuse designed to provide reliable overcurrent protection in a wide range of electronic applications. As an authorized distributor, Supreme Components International offers this high-quality component, ensuring authenticity and performance. This resettable fuse has a hold current of 1.2A and a maximum voltage rating of 250V. When an overcurrent condition occurs, the fuse heats up and increases its resistance, limiting the current flow and protecting the circuit. Once the fault is removed and the device cools down, it automatically resets, restoring the circuit to normal operation. This feature eliminates the need for manual fuse replacement, reducing downtime and maintenance costs. The RLD120PO25X is suitable for applications such as power supplies, battery chargers, and consumer electronics.
