Introduction to 17AM Thermal Protector

The 17AM thermal protector switch is a thermal protection element that uses a special bimetallic reed, a large-capacity contact, a conductive metal shell and a bottom plate to form a control loop. It has the advantages of small size, fast temperature sensing, reliable performance, etc. It can be fully automated in large quantities and is widely used in the field of thermal protection.


The working principle of 17AM thermal protector

When working, the bimetal reed presses the movable contact on the static contact tightly due to the special curved surface, the contact is closed, and the circuit is turned on. When the electrical appliance generates heat due to a fault, and the temperature rises to the rated operating temperature of the thermal protector, the bimetallic element is heated to generate internal stress and quickly act to reverse the arc, driving the moving contact to instantly jump away from the static contact, causing the contact to break Switch on and cut off the power supply to protect against overheating. When the temperature of the protected electrical appliance drops to the product's rated reset temperature value, the bimetallic element returns to the initial state and the movable contact is closed, and the electrical appliance resumes work.

17AM Thermal Protector Instructions

The product shell is made of metal material, and the shell is live when it is energized. It has been equipped with a high-temperature thermally conductive polyester insulation protective sleeve when it leaves the factory. When installing, check whether the thermal protector is placed in the middle of the insulation sleeve, and the insulation sleeve must not be removed. installation.

Do not knock with sharp objects or hard objects to prevent deformation of the shell during installation. Do not install in a humid environment with a humidity greater than 90% or directly immerse in liquid to avoid accidents due to shell deformation, product failure or shell leakage; installation wiring should Pay attention to the good connection of the lead wire to avoid causing the virtual connection to generate heat and affect the normal operation of the thermal protector.

The actual working voltage and working current of the thermal protector should not be greater than its nominal rated voltage and rated current, and it can be used normally if it is less than its nominal rated voltage and rated current.
