Working principle
Before the action, at normal operating temperature, the current from one end of the lead through the metal case, contact, to the other end of the lead wire contact line) so that the circuit is open (and vice versa).
After the action, when the equipment is in normal working condition, due to the temperature rise, reaching the set temperature of the thermal fuse, the temperature-sensitive body melts, the drum spring automatically relaxes, the contact plate moves under the action of the direct spring, resulting in the contact plate and contact line break circuit is cut off.
Caution
1, lead bending use, should be bent from the root of more than 6 mm from the parts; bending, shall not damage the root 1 and lead, shall not be forced to pull, press, twist the lead.
2, thermal fuse body using screws, riveting or terminal block fixed way, should be able to prevent mechanical creep and ten million poor contact phenomenon.
3、Connecting parts should be able to work reliably in the working range of electrical products, will not occur due to vibration, shock and 3 displacement.
4, lead welding operations, the heating humidity should be limited to a minimum, take care not to add high temperature on the thermal fuse 4 shall not be forced to pull, press, twist the thermal fuse and lead; welding is completed, should be immediately cooled for more than 30 seconds.
5, the thermal fuse body can only be used under the conditions of the specified rated voltage, current and specified temperature, especially pay attention to the thermal fuse body can withstand the maximum continuous temperature. Note: Nominal current, length and temperature of fuse can be designed according to customer's requirements.
