What is the difference between a thermal circuit breaker and a fuse? How should we distinguish between thermostats, temperature limiters, thermal circuit breakers and protection devices? Today for you to recommend is the knowledge of these two aspects, it can be learned, first of all, the role of the thermal circuit breaker is to reach a certain temperature automatically disconnect the circuit, but the role of the fuse is to play a protective function, so it should be analyzed on a case-by-case basis. Secondly, there are a lot of similar products, the first choice of friends may be difficult to distinguish the difference between the specific can be considered in conjunction with the actual needs through the above, I believe that we can achieve satisfactory results and the ultimate goal.
One, what is the difference between a thermal circuit breaker and a fuse
The role of the thermal circuit breaker is to reach a certain temperature to automatically disconnect the circuit ...? And the role of the fuse is "current" more than the load of the FUSE fuse circuit
2, how to distinguish between the thermostat, thermostat, thermal circuit breaker and protection device
1, thermostat and thermostat thermostat, thermostat, thermostat is the appliance in the normal operation of the role during the temperature control elements. Difference: - thermostat by disconnecting or connecting the controlled circuit, the controlled temperature is limited to a range. The operating characteristics of a thermostat can be loosely compared to "two-way operation". For example, the temperature control element in an electric water heater is the thermostat. The thermostat is adjustable. --A thermostat limits the controlled temperature below or above a certain temperature point by breaking or turning on the controlled circuit. The operating characteristics of a thermostat can be loosely compared to "one-way operation". For example, the temperature control element in an electric kettle is a thermostat. The thermostat is not adjustable.
2, thermal circuit breaker definition: thermal circuit breaker is the appliance in the non-normal operation during the role of the temperature control element. Note: 1) in the appliance and its electrical accessories industry, often the temperature control element commonly or collectively known as thermostat. However, when it comes to the concept of this standard, must be the normal operating conditions of the action of the temperature control element - thermostat, and non-normal operating conditions of the action of the temperature control element - thermal circuit breaker strictly different. 2) Similarly, the industry can be seen in the thermal circuit breaker and thermostat in the designation, appearance and shape, nominal parameters and so on is not necessarily separate, and do not have to be separate. A temperature control element, only to be applied to the appliance, to clarify its specific control purpose, only with the definition of the specific meaning. 3) With PTC elements made of thermal circuit breaker is to limit the temperature by reducing the current. 4) Thermal circuit breaker has a self-resetting and non-self-resetting points. An air switch needs to be reset manually after operation. Thermal fuses need to be reset with a new part after operation.
3, protective devices 1) the types of protective devices at least - for temperature anomalies in the protective devices, such as thermal circuit breakers. -To the current abnormal protective device, such as current fuse, etc.. -Protective devices against mechanical hazards, such as pressure relief devices, interlocking devices for food processing equipment. -Artificially installed weak links in appliances or in electrical circuits. -Protective devices against other hazards, such as microwave oven door interlocking devices, etc. 2) The protective devices here do not include certain protective structures, such as insulated structures, waterproof structures, etc.
Today not only for you to recommend the circuit breaker and fuse the difference between their respective differences, but also give you the skills to distinguish between thermostats, circuit breakers and protection devices, some of the key parts, which can be used to play a common role in the temperature control of the software is what we usually call the thermostat, and the thermal circuit breaker, then the main is to reach a certain temperature can be automatically disconnect the circuit, play a protective function purpose. Circuit, to protect the functional purpose, the fuse is similar, but the two may be different for the place requirements, the specific circumstances should be specifically analyzed, combined with the actual understanding, or reference to professional advice to make the final judgment program.
