For example, much of the design work for PCs, peripherals, and portable devices urges the use of PTCs because they are self-resettable; using a fuse that must Fuses do in fact interrupt the current flow in response to the overload and the.
A resettable fuse is a polymeric positive temperature coefficient (PPTC) device that is a passive electronic component used to protect against overcurrent faults.
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.
What is the basic working principle for this, Is it so that when current goes beyond the rated value its resistance increases, but whether this.
Like traditional fuses, these devices limit the flow of dangerously high current How a PolySwitch Device Works. Polymer Typical PTC Application. Figure 2. R .
Resettable fuses are designed and made of patented novel polymeric PTC The device does not trip at or below its rated Hold Current, and will trip at or above.
