说明(Instruction)
TH-B型系列热保护器,广泛用于工业、家用电器的塑料电机及电气设备,*因过流、过热而产生的非正常工作提供*的*保护。外壳才采用*,热传导快的*度PBT工程塑料制造,适用于塑封电机外置式安装及家用电器的*保护。

TH-B series thermal protector are widely used in electric motors of industrial、household appliance & other electric equipment. The TH-B series can effectively and reliably guard against the damage caused by overflow and overheat. The shell is made from heat resistant and heat conductive PBT engineering plastic. The product is applicable to the externally installed plastic sealed motors and household electric appliance.

结构及保护原理(Configuration & principles)
TH-B型系列热保护器是由导热塑料外壳,焊有银合金触点的双金属元件、导电支架、*缘固定座、静触片及耐热导线等元件组成。电流通过有阻*的双金属元件,遇非正常工作时,随电流*或周围温度升高至设定温度值时,双金属元件*动作,打开触点,切断电路。当装置冷却到*工作温度时,触点自动闭合,恢复正常工作状态。

TH-B series thermal protector is compised by heat conductive plastic shell, bimetal component welded silver alloy contact, current conductive frame, insulated fixing seat, static contant pad and heat resistant wires etc. When the current goes through the bimetal component with impedance, if the current increases or the environment temperature rises and the temperature reaches the preset value, the bimetal component will work and release the contact to shut off the circuit; and by contrast, if the device cools down to the temperature, the contact point will reset automatically.

说明:TH系列均采用统一机芯,型号之分*为外壳的外形尺寸不同。

Instruction:The TH Series Theory of every t*e is same, except for difference of caze size.
