(Instruction) BH-B series thermal protector are widely used in electric motors of industrial、household appliance & other electric equipment. The BH-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) BH-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.
