17AME+PTC is the assembly of a 17AME protector and a heating PTC. It has power cut and self-hold functions,which makes it safer than common auto reset model. It is applicable to the over-heat and over-current protection of vacuum cleaner, blender,mixer, grass cutter and electrical tools.
Special Features
With power protection, delay protection function;
More safe and reliable performance;
Better suited to abnormal motor protection.
Casing seal to prevent insulating paint like substance immersion.

Working Principle:
The protector is connected to PTC in parallel, then connected to application in series. when the application is working normally. then current will flow through protector. PTC will not work.
When the application works abnormally, which causes the ambient temperature exceeds the prescribed value, the protector will open. Then, the current flows through PTC, Since PTC has a very high resistance, the current assigned to the application will be too low to start it. Meanwhile, the heat generated by PTC will remain the protector open until the power is unplugged.
After the power is unplugged, the ambient temperature will decrease and then, the protector will close again.

PTC thermistors current protector, also called PTC thermistor resettable fuses, protect load against over-current, overload, short circuit. No need for replacement, resume protective function after a short cooling-down time. Ceramic PTC (positive temperature coefficient) thermistors are used instead of conventional fuses to protect load, such as motors, transformers, or electronic circuit, against overcurrent for circuit protection. PTC thermistor protector not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded. PTC thermistor over-current protector limits the power dissipation of the whole circuit by increasing their resistance and thus reducing the current to a harmless residual value. In contrast to conventional fuses, PTC thermistor resettable fuses do not have to be replaced after elimination of the fault but resume their protective function immediately after a short cooling-down time. PTC Thermistor Over-current Protector Application It applies in the over-current overload and short circuit protection of transformers, battery charger, switches, switch power supply, adaptor, meter, instrumentation, apparatus, electronic coils, control panels, air conditioner, automotive electron, etc. Operating Principle of PTC Thermistor for Overload Over-current Protection The operating principle is as indicated in the following. When a circuit is in the normal status, the current through PTC is lower than the rated current and PTC thermistor protector is in the normal state with small resistance value, which will not affect the normal operation of the protected circuit. In case of some fault in the circuit and the current is greater than the rated current, the PTC thermistor protector will become hot quickly and present a high resistance state, which sets the circuit relatively "off" to protect the circuit from damage. After the fault is removed, PTC thermistor protector will automatically restore its low resistance state and the circuit will resume normal operation. Normally, when PTC thermistor is used as an overcurrent protection component, it is preferred to select maximum operating current, maximum operating voltage and proper specifications. Furthermore such factors should be taken into consideration as the dimensions of the components, rated zero-power resistance, operating temperature range, etc.
