RL72-135 PTC Resettable Fuse 1.35A High Stability Protection Fuse | RUILON

The RUILON RL72 Series Positive Thermal Coefficient (PTC) resettable fuses are high-performance overcurrent protection devices designed for medium to high-power electronic and industrial applications. These components automatically increase resistance during fault conditions such as short circuits or overloads, effectively limiting current flow and protecting sensitive circuits.

The RL72 series provides enhanced current handling capability, stable trip performance, and reliable reset functionality, making it suitable for power systems, industrial electronics, and high-reliability protection circuits. It ensures fast response to fault conditions while maintaining low resistance during normal operation.
