- AUPO thermal protector is resettable thermal protection device used for overheating protection of household appliances and industrial equipment. When ambient temperature rises to its functioning temperature, the thermal protector will sense the external temperature state and cut off the circuit.

- CA05 thermal protector consists of base, static contact, movable contact, bimetallic sheet, outer case,electronic wire, insulating sleeve and other parts. It reliably senses the change of the ambient temperature. When ambient temperature reaches its functioning temperature, the bimetallic sheet will work and the movable contact disconnect with static contact, thus cutting off the circuit for overheating protection.
Advantages:
- 1. Selection of American MES bimetallic sheet, stable performance and high reliability.
- 2. The service life is over 10000 times.
- 3. Passed safety test and certification of temperature limiter and motor thermal protector.
- 4. Epoxy package, good product sealing.
- 5. There are metal case and plastic case version, easy for selection and installation.
Application Field:
- CA05 series products are used for overheating protection of fractional horsepower motors, electric heating appliances, fluorescent lamp ballasts, transformers, integrated circuits and general electrical equipment.
Product Certification:
- CA05 series thermal protector has passed safety tests of UL 60730-2-2, UL 60730-2-9, EN 60730-2-2, EN 60730-2-9, GB/T 14536.3-2008, GB /T 14536.10-2008, and are certified with UL, TUV, CQC and other safety approvals.
