  2. Thermal cutoff - Wikipedia

    en.wikipedia.org/wiki/Thermal_cutoff

    Thermal switches are used in power supplies in case of overload, and also as thermostats, and overheat protection in some heating and cooling systems. They are found in virtually every refrigerator, microwave, clothes dryer, space heater, and many more appliances found throughout the home.

  3. Magnetic starter - Wikipedia

    en.wikipedia.org/wiki/Magnetic_starter

    A magnetic starter has a contactor and an overload relay, which will open the control voltage to the starter coil if it detects an overload on a motor. [1] [2] The overload relay opens a set of contacts that are wired in series with the supply to the contactor feeding the motor. The characteristics of the heaters can be matched to the motor so ...

    23 – Temperature control device, Heater; 24 – Volts per Hertz Relay (in some old analog applications, a 59 and an 81 device would be chained together as a 59/81 to implement the equivalent of V/Hz protection) 25 – Synchronizing or Synchronism-check Device; 26 – Apparatus Thermal Device, Temperature Switch; 27 – Undervoltage Relay

  5. Furnace (central heating) - Wikipedia

    en.wikipedia.org/wiki/Furnace_(central_heating)

    A furnace (American English), referred to as a heater or boiler in British English, is an appliance used to generate heat for all or part of a building. Furnaces are mostly used as a major component of a central heating system .

  6. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    An optimized heater design helps to control the heating power and modulate the local temperatures across the heater substrate. In cases where there is a requirement of two or more heating zones with different power densities over a relatively small area, a thick-film heater can be designed to achieve a zonal heating pattern on a single substrate.

  7. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    A district heating system uses centrally located boilers or water heaters and circulates heat energy to individual customers by circulating hot water or steam. This has the advantage of a central highly efficient energy converter that can use the best available pollution controls, and that is professionally operated.

  8. Induction heater - Wikipedia

    en.wikipedia.org/wiki/Induction_heater

    Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.Supply (mains) frequency 50 Hz or 60 Hz induction heaters incorporate a coil directly fed from the electricity supply, typically for lower power industrial applications where lower surface temperatures are required.

  9. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    Architectural style wiring diagram, with lamps and switches shown symbolically in their physical locations on the plan view of the building. Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building.
