ekThe A250-120 PTC Resettable Fuses with Through Hole RoHS, manufactured by JDTek, are a type of self-resetting circuit protection device designed to protect against excessive current caused by overload, short circuit and other circuit faults. This device features a polymer-based Positive Temperature Coefficient (PTC) element that quickly reacts to fault conditions, allowing instantaneous disconnection of the circuit during an overcurrent condition. After disconnection, the device will automatically reset when the fault condition has passed and the restored normal current level is below the specified threshold for the device. These resettable fuses provide protection up to 250 Volts and a maximum Interrupting Current rating of 120 Amps. With a RoHS certification, the A250-120 is made out of environmentally friendly materials and is compliant with current industry regulations.
