Reinforced shell (PBT metal case, plastic case) for motor built-in installation, Can withstand 3. 5Mpa plastic molding process pressure. Product performance in line with IEC34-11, GB13232, GB / T13002 and other standards. Such as: KSD9700 temperature control switch, BW9700 temperature switch, TB02, KW thermal protection, and so are temperature control switch 9700 series.
Structure and protection principle (Configuration & principles)
    Thermostat 9700 Series Thermal Protector is a thermally conductive metal case nickel plated SPCC, plastic case PBT. A bimetal element with a silver alloy contact,
Conductive support, insulation fixed seat, moving contact, static contact, Epoxy sealant, And wires and other components. Current through the impedance of the bimetal element, When the temperature of the heating element rises to the set temperature value, The bimetal element moves rapidly, Open the contact, cut off the circuit. After years of research and development, 9700 series temperature control switch to meet the requirements of the heater, Products to miniaturization, High current development. Current commonly used product size, current has the following standards:
Product size corresponds to different current: (L * W * H)
(Minimum size 15 * 5. 4 * 2. 4 3A / AC125V, 2A / AC250V)
(Conventional size 20 * 7.6 * 4, 8A / AC125V, 5A / AC250V),
(TB10 series 18 * 7.9 * 3.5, 12A / AC125V, 10A / AC250V)
(High current TB25 series 22 * 9 * 4, 30A / AC24V, 25A / AC250V)
(High current TB50 series 25 * 10.6 * 5.2, 60A / AC24V, 50A / AC250V)
Available temperature: 30 ℃ ~ 160 ℃, to 5 ℃ for a temperature range
Reset temperature range: less than the rated breaking temperature (20 ℃ ± 10 ℃)
Safe working temperature,
Moving contact and static contact piece again connected to electricity,
Restore normal working condition.
  Temperature Switch KSD9700 Series Configuration (Package Configuration)



Temperature Controlled Switch KSD9700 Series Attention
1, the use of contact temperature-type installation, The metal cover should be close to the mounting surface of the controlled device, To ensure that the temperature effect, Should be coated in the surface temperature of thermal silica gel or other similar performance of the medium.
2, the installation can not be crushed when the shell, loose or deformation, So as not to affect performance.
3, can not let the liquid into the temperature controller internal, Shall not make the shell cracks, Do not change the shape of the external terminal.
4, the product is not greater than the rated current of the circuit used in the product, Should choose the copper core section for 0. 5-1 mm2 wire connection;Not more than 10A current used in the circuit, Should be selected copper conductor cross-section 0.75-1.5 mm2 wire connection.
5, the product should be less than 90% relative humidity, Ambient temperature below 40 ℃ ventilation, clean, dry, non-corrosive gas storage warehouse.

4, temperature control switch KSD9700 series life
    Products in the rated voltage, current, power factor of 0.7 conditions(In the AC circuit, The cosine of the phase difference (Φ) between the voltage and the current is called the power factor, Denoted by the symbol cosφ. numerically, The power factor is the ratio of the active power to the apparent power, cosφ = P / S)External heat source to make it move 6000 times, Should meet the following conditions:
A. Disconnect the temperature change should be within the initial value of +5 ℃;
B. Contact resistance should be less than 100mΩ;
       Continue to test to 10,000 times after the action.
