Miniature thermal protector
When the electric appliance works for too long or abnormal temperature rises to the action temperature set by the protector, the bimetallic sheet acts rapidly due to the internal stress generated by thermal, so as to effectively disconnect or connect the circuit. This plays the role of temperature control to a certain extent.
When the electrical cooling returns to the set reset temperature, the contact of the thermal protector will automatically close/open and return to the normal working state.
Thermal protectors are widely used in motors, motors, electric thermaling appliances, air conditioners, and other electronic products because of their low production cost and accurate and stable operating temperature.
thermal protector Precautions for installation:
1. When the lead is used in bending, it should be bent from the parts more than 6 mm from the root; When bending, do not damage the root and lead, do not force pull, press, twist the lead.
2. When the
thermal protector is fixed by screw, riveting or binding post, it should be able to prevent the mechanical creep and the occurrence of millions of bad contact phenomena.
3. The connected parts shall be able to work reliably within the working range of electrical products, without displacement due to vibration and impact.
4. During lead welding, the thermaling humidity should be limited to the minimum, and high temperature should not be applied to the hot fuse. The hot fuse and lead shall not be forcibly pulled, pressed or twisted. After welding, it should be cooled for more than 30 seconds immediately.
5. The thermal protector can only be used under the conditions of specified rated voltage, current and specified temperature. In particular, attention should be paid to the maximum continuous temperature of the thermal fuse. Note: Nominal current, lead length and temperature can be designed according to customer's requirements
