The RL30-200 with PTC Resettable Fuses Through Hole RoHS is an electronic part designed and manufactured by Ruilongyuan. This unique electronic component is an effective overcurrent protection device for wires, circuits, control cabinets, and solenoid valves, among other equipment. It features PTC (positive temperature coefficient) resettable fuses, which automatically reset after the overcurrent is eliminated. These PTC resettable fuses are located in through-holes in the RL30-200, which allows the fast, easy, and secure mounting of the component to a wide variety of small and large systems. The RL30-200 also meets the EU directive RoHS (restriction of hazardous substances), so it is safe for use in hazardous environments.
