thermal link: thermal cut-out which operates only once and requires partial or complete replacement It is a temperature sensing device, but it can only be operated once, when the temperature is higher than its set value, it will disconnect, and after disconnection, the current can not pass through, so as to play the role of…
thermal-cut-out: device which during abnormal operation limits the temperature of the controlled part by automatically opening the circuit, or by reducing the current, and is constructed so that its setting cannot be altered by the user. There are three key provisions here. First, the thermal cut-out is a heat-sensing element, second, it can only be…
heating appliance: appliance incorporating heating elements but without any motor. Before introducing this definition, we need to briefly introduce the electric heating elements commonly used in household electrical appliances. PTC heating element: PTC (Positive Temperature Coefficient) heating elements are widely used for various heating applications because of their self-regulating properties and safety features. Here are…
protective electronic circuit: electronic circuit that prevents a hazardous situation under abnormal operating conditions.NOTE Parts of the circuit may also be used for functional purposes. With the advancement of technology, more and more electronic circuits are being used in household electrical products, and these electronic circuits are usually integrated on PCBs. They use microprocessor chips…
