Polyswitch

Un fusible réarmable CTP (CTP = coefficient en température positif), ou fusible réarmable PTC (nommé en anglais polymeric positive temperature coefficient device (PPTC) - ou plus généralement polyfuse ou polyswitch ) est un composant électronique passif utilisé pour protéger contre les défauts de surintensité dans les . A resettable fuse is a polymeric positive temperature coefficient (PPTC) device that is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a polyfuse or polyswitch. They are similar in function to PTC thermistors in certain situations but operate on . Ideal for situations where frequent overcurrent conditions occur or constant uptime is require .

A - 1ARHEF1ou tout autre fusibles-a-terminaison-a-fil-rearmables sur fr. Under normal operating conditions, the heat generated by the device and the heat lost by the device to the environment are in balance at a relatively low temperature, as shown in Point of Figure 3. PolySwitch device operation is based on an overall energy balance. If the current through the device is increased while the . The Problem of Overcurrents. An overcurrent is an abnormally high current that has the potential to cause failure in an electrical circuit.

An out-of-range condition in the power source or a decrease in load impedance can cause an overcurrent. The use of PPTC devices as a variable resistor in circuit protection applications was first pioneered by Raychem several decades ago.
