Temperature protector
TH-B series thermal protection, and are widely used in industry, plastic electrical household appliances and electrical equipment to prevent over-current, overheating caused by the work of non-normal to provide an effective and reliable security. Case only the use of high temperature, thermal conductivity of high-intensity fast PBT engineering plastic manufacturing, plastic motor for installation and external security appliances.
Structure and the protection of the principle of
Series TH-B-type thermal protection is from thermal plastic shell, welded contacts are silver alloy components of the bi-metallic, conductive frame, insulated mounting, static touch, such as films and heat-resistant wire components. Current through the bi-metallic element impedance, when non-normal working hours, with the current increase or the surrounding temperature to set temperature value, the dual-metal components action quickly, open the contact, cut off the circuit. When the device cooled to a safe working temperature, contact automatically closed, return to normal working condition.
Note: TH series are unified movement, the sub-models is only a different form factor case.
