AMWEI - PTC Thermistor for Circuit Overload Over-current Protection
PTCthermistorsCircuit Protector, also calledPTCthermistorResettable fuse, are used instead of conventional fuses to protect load, such as motors, transformers, or electronic circuit, against overcurrent for circuit protection.PTCthermistorsprotector not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded.PTCthermistorover-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,PTCthermistorresettable fuses do not have to be replaced after elimination of the fault but resume their protective function immediately after a short cooling-down time.
AMWEI - PTC Thermistors Heater
PTC Thermistors (thermal resistor), also called PTC stone, are ideal heating elements. Thanks to self-regulation properties, heating devices based on PTC thermistor technology can generally dispense with control and regulating components as well as with over-temperature protection, PTC thermistor heating elements are used wherever measurement and regulating equipment as well as heating devices must be housed in tight confines. PTC Heating elements can be designed to be square, rectangular, round, ring or doughnut form, or housed in aluminum, stainless steel, silicon casing.
