1. When the conductor is bent, it should be bent from a position more than 6 mm away from the root; When bending, the roots and leads shall not be damaged, and the leads shall not be forcibly pulled, pressed or twisted. 2. When the thermal fuse body is fixed with screws, rivets or terminals, it should be able to prevent mechanical creep and poor contact. 3. The connector should be able to work reliably within the working range of electrical products and will not be displaced due to vibration and impact. 4. During the lead welding operation, the heating humidity should be limited to a minimum, and care should be taken not to increase the high temperature of the thermal fuse; Do not forcibly pull, press or twist thermal fuses and wires; Immediately after welding, it should be cooled for more than 30 seconds. 5. Thermal fuses can only be used under the specified rated voltage, current and specified temperature conditions, and special attention should be paid to the maximum continuous bearing temperature of thermal fuses. Remarks: Nominal current, lead length and temperature can be designed according to customer's requirements.

Thermal protector can be called temperature control switch or thermostat or thermal protection switch or temperature switch.

general requirements

Thermal protector and motor are integrated in structure and function to form a thermal power system. As a heater, the motor affects the heating and cooling speed of the protector. The reliability and performance of thermal protector should be tested by installing protector in motor.

The requirements of this standard apply to a single motor or one motor in a series of motors and thermal protectors.

When using thermal protector, it is necessary to determine whether the thermal protector is self-healing or non-self-healing. Generally speaking, the self-healing thermal protector can be used unless the unexpected restart of the motor may cause danger or damage to the user. Examples of applications requiring non-repair protectors are: fuel engines, waste food processors, conveyor belts, etc. Examples of applications requiring self-recovery thermal protectors are refrigerators, electric washing machines, electric dryers, fans, pumps, etc.

According to the nature of action, it can be divided into normally open action and normally closed action.

According to volume: it can be divided into conventional large volume and ultra-thin type.

Example: The following are ultra-thin volumes 16*5.2*3. Specially used for battery packs and electric heating products!

● Working principle of ●KSD9700 thermal protector

KSD9700 series products are a kind of thermal protector with bimetal as temperature sensing element. When the electrical appliance works normally, the bimetal is in a free state and the contacts are in a closed/open state. When the temperature rises to the working temperature, the bimetallic element generates internal stress and moves quickly, opening/closing the contact and cutting/connecting the circuit, thus playing the role of thermal protection. When the temperature drops to the set temperature, the contacts automatically close/open and return to normal working condition.
