HOW DOES THE RESETTABLE FUSE WORK
PPTC resettable fuses are designed and made of patented Polymeric PTC (PPTC) material in thin chip form. It is placed in series to protect a circuit. At “normal operating condition” the device remains at an extremely low resistance and allows the electrical current to flow through it without any restriction. When overcurrent conditions occur, the Polymeric PTC material heats up and its resistance increase sharply. Such a sharp resistance increase cuts off the current in the circuit. Upon fault current being removed, the resettable fuse cools and its resistance drops to the original extremely low value. The resettable fuse is “reset” and allows the current through the circuit again.
Warning !
— Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or flame.
—PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged trip are not anticipated.
—Avoid contact of PPTC device with chemical solvent. Prolonged contact will damage the device performance.
