Electric heater thermal protector
The product is applicable to the thermal radiation control on various electric heating appliances including electric heaters, warm air blowers, dehumidifiers, etc. Never touch wire protector or temperature sensor during the installment and utilization of thermal protectors, or it will lead to the failure of protectors because of inaccurate temperature and loose contact.

|Operating Temperature:||50-150 (one step for every 5℃)||Standard Tolerance:||±5℃|
|Reset Temperature:||Operating temperature decrease by 15-45℃||Contact Closure Resistance:||≤50mΩ|
|Insulation Resistance:||≥100MΩ||Service Life:||10000 times|
●Quickly respond to the variation of temperature;
●No current flows through bimetallic strip so the influence of self-heating effect is avoided and it leads to a long service life with little change in temperature;
●Environmental friendly high-power silver contact is adopted, being accord with the requirements of safety approval for export;
●PTC component and contact circuit form a parallel circuit. With the heading up of temperature, contact circuit is off and current flows through PTC component to form a loop. The temperature of PTC component increases rapidly, being higher than rated reset temperature and keeping the circuit in the off state. When the general power is off and temperature decreases to the reset temperature of bimetallic strip, the strip recovers rapidly and contact closes, providing a safer and more reliable protection on circuits.
●Installment with bracket is available, being easy for direct fixing.
