250V 10A 20A 30A 40A 50A Radial Lead Thermal Cutoff Fuses
10A 20A 30A 40A 50A Thermal Cutoff Fuse 250V Radial Lead Square Type Lightning Protection
Description of 10A 20A 30A 40A 50A Thermal Cutoff Fuse
The Y series thermal cutoff is an unresettable thermal protect instrument. It is used in household appliances and industry instrument for thermal protecting. When an ambient temperature of the thermal cutoff rises to an abnormal temperature, the thermal cutoffs tastes the ambient temperature and open the circuit. Its all-sealed structure insures the stability and reliability, and it is not influenced by ambient humidity and so on. Its main features are: extremely sensitive to ambient temperature; precise and stable functioning temperature; compact, epoxy-sealed structure; reliable, approved by various international safety standards.
Structure of Square Type Thermal Cutoff Fuse
The thermal fuse is composed of plastic shell, low melting point alloy wire, special resin, lead copper wire and sealing resin.
