H20 Temperature Thermostat Switch , 18.5 Length Bimetal Temperature Switch

H20 Heating Thermostat,H20 Bimetal Temperature Switch

Product Description

BW series thermostat / 9700 thermal protector / BW9700 temperature protector 1. BW series thermostat's Principle and structure BW serial universal and enhanced protectors with large metal casing are composed of the thermal conductive metal casing, bimetallic parts welded with silver alloy contact point, conductive bracket, insulation fixation stand, fixed contact strip and heat resistance cable. In case of abnormal operation, along with the increase of the environment temperature to the set value, the bimetallic parts perform quick action, open the contact point, and disconnect the circuit. When the device is cooled to the temperature for safe operation, the contact point will automatically closes and recover normal operation. 2. BW series thermal protector's Specification 2.1. Switch type: normally closed, normally opened. 2.2. Operating Voltage / Current: AC250V / 5A; AC125V / 8A 2.3. Operating Temperature: 40~150℃ (one step for every 5°C) 2.4. Standard Tolerance: ±3°C / ±5°C / ±7°C 2.5. Reset temperature: operating temperature decrease by 15-45°C 2.6. Contact Closure resistance: ≤50mΩ 2.7. Insulation resistance: ≥100mΩ 2.8. Electric strength: AC1500V/1min free from phenomena of break down and flashover. 2.9. Service life: 10000 times 3. BW series thermal protector's Dimension Model Length width High BW9700 20 7.3 3.8 4. BW series temperature protector's Application BW series is applicable to chargeable battery, ballast, massager, micro motor, transformer, electric tools, heat electric appliance and instrument etc. The product UL,CQC,VDE and RoHS certification approval.
