non-self-resetting-thermal cut-out: thermal cut-out that requires a manual operation for resetting, or replacement of a part, in order to restore the current.NOTE Manual operation includes disconnection of the appliance from the supply mains. The thermal cut-out is equipped with a temperature-sensitive component, typically a bimetallic strip or a thermistor, which reacts to heat. As the…
electronic component: part in which conduction is achieved principally by electrons moving through a vacuum, gas or semiconductor.NOTE Neon indicators are not considered to be electronic components. Early vacuum tubes were components that allowed electrons to conduct in a vacuum and were the core components of old radios and televisions.Electrons move through specific gases, colliding…
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…
visibly glowing heating element: heating element that is partly or completely visible from the outside of the appliance and has a temperature of at least 650 °C when the appliance has been operated under normal operation at rated power input until steady conditions have been established. The heating element needs to be able to emit…
25.20: The conductors of the supply cord for type Y attachment and type Z attachment shall be insulated from accessible metal parts by basic insulation for class 0 appliances, class 0I appliances and class I appliances, and by supplementary insulation for class II appliances. This insulation may be provided by the sheath of the supply…
hand-held appliance: portable appliance intended to held in the hand during normal use. Hair dryers, electric irons, hand-held vacuum cleaners, etc. are typical examples of hand-held appliances.
