Thermal Cutoff Fuse for Fractional Motor

BW series thermostat / KSD9700 thermal protector / BW9700 temperature protectorH20,H21 series thermostat's Principle and structureH20,H21serial 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.H20,H21series thermal protector's SpecificationSwitch type: normally closed, normally opened.Operating Voltage / Current: AC250V / 5A; AC125V / 8AOperating Temperature: 40~150ºC (one step for every 5°C)Standard Tolerance: ±3°C / ±5°C / ±7°CReset temperature: operating temperature decrease by 15-45°CContact Closure resistance: ≤50mΩInsulation resistance: ≥100mΩElectric strength: AC1500V/1min free from phenomena of break down and flashover.Service life: 10000 timesH20,H21series thermal protector's DimensionModelCaseLengthwidthHighLead wireH20Plastic18.584#22 3266 white, or according client' requesH21metal18.57.33.8#20 3135 red, or according client' request
