Operating theory

• 

• [DRAWING 1]

  The current start to flow through the arrow direction
  Lead connection – can crimp
  Terminal – bimetal disc – matching contact
  

• 

• [DRAWING 2]

  When the current or temperature is rising, the heat is
  Generated or transferred to bimetal disc.
  The disc snaps open at calibrated open-temperature

• 

• [DRAWING 3]

  The disc snaps closed when the
  Disc cools down up to the reset-temperature
