Current type overload protector: Triggers protection based on the magnitude of the induced current. Combined type (temperature + curre...Read more -
The working principle of magnetic control switches
The magnetic control switch is composed of reed switches, permanent magnets and temperature-sensing soft magnets. Its core function is to automatically control the on and off of the circuit according to temperature changes. The specific working process is as follows: Low-temperature environmental...Read more -
Two major classifications of magnetic control switches for refrigerators
The magnetic control switches used in refrigerators are mainly divided into two categories: low-temperature magnetic control switches and ambient temperature magnetic control switches. Their function is to automatically control the on and off of the low-temperature compensation heater to ensure t...Read more -
The practical application scenarios and maintenance advantages of the design of heating tubes with double fuses
In practical application scenarios, the first one is a defrosting circuit failure: if the defrosting temperature controller fails, the heating tube may continue to work, and the dual fuses can intervene in stages. Secondly, in case of short circuit or insulation damage: When the current suddenly ...Read more -
The function of the design in household refrigerators that uses heating tubes with dual fuses
The heating tubes in a refrigerator (such as defrosting heating tubes) are mainly used for: defrosting function: Regularly melting the frost on the evaporator to maintain the cooling efficiency. Prevent freezing: Maintain a slight heating in specific areas (such as door seals) to prevent condensa...Read more -
The advantages of stainless steel heating tubes
