What is the thermal limit value?
Thermal limit value is a device used to interrupt the electrical circuit when it reaches a certain temperature. By cutting off electricity at certain temperatures, this type of device protects other components of the circuit from damage. It is available in two varieties: thermal fuses and thermal switches. The thermal fuse is a consumer thermal limit that is used once and then replaced. The thermal switch can be reset after cooling to a safe operating range. They are usually used in domestic devices such as hair dryers and kitchen equipment. The thermal fuse usually consists of metal pellets and spring closed in the classroom. When the perimeter overrides, the pellet melts and the spring pushes electrical contacts apart and breaks the circuit. The thermal fuse differs from the traditional fuse in that it is activated only by the temperature and not the excess electrical current.
The thermal switch is used in circuits that are more likely to overheat in their normal operation. This oneThe air can also be used in circuits that overheat as a result of a natural user error. Common applications of the thermal switch include home electronics, workshops, fluorescent lamps and power units. The thermal limit device is also called a reset switch because it can be reset after the device has cooled to a safe operating temperature.
As part of the electrical circuit, the thermal limit device provides protection from the insulation of the wiring, components and fire damage. This type of device is usually produced with demanding specifications that specify exactly where the specific closing point of the thermal limit is. This closure point is called the evaluation of the device. The relevant evaluation of the FPEBO limit device will decide on the use in the system to determine the highest safe operating temperature of individual components. The lowest of these temperatures is correct thermal marginal evaluation.
in someIt is the ability to reset itself intentionally to use it as part of the functional design of the perimeter. The flashing Christmas lights are one of the most famous examples of this type of design. When the metal strips are heated in thermal restriction, the thermal switch opens and breaks the circuit. This causes the lights to burn and cool and reset the switch. This process is called cycling.
