The Ruilongyuan RL30-600 with PTC Resettable Fuses Through Hole RoHS is a reliable, RoHS compliant, electronic component that can provide overcurrent, overvoltage and short circuit protection. It is an one-time use, resettable, surface mount device that offers a wide range of current protection levels up to 600A. It features polymeric positive temperature coefficient (PPTC) technology, which quickly detects an unusual current level before it can cause dangerous damage and immediately disconnects the electrical power supply. The RL30-600 is designed with high leakage resistance, good temperature characteristics, compact size, and a long service life. It is a perfect choice for solid-state systems in telecommunications, automotive electronics, and other industrial applications.
