RL250-500 PTC Resettable Fuse 0.5A Power Circuit Protection Component | RUILON

The RL250 Series Positive Thermal Coefficient (PTC) resettable fuses are high-voltage overcurrent protection devices designed for industrial, power, and advanced electronic applications. These components protect sensitive circuits by automatically increasing resistance when excessive current flows, thereby limiting fault current during short circuits or overload conditions.

The RL250 series supports up to 250V operation and offers a wide range of current ratings from ultra-low to high current levels. It features stable trip characteristics, fast response time, and automatic recovery after fault removal. Its robust construction ensures reliable long-term performance in demanding electrical environments.
