PTC heating element
60 - 275 W
Vulcanic
PTC resistors combine two technologies: electric
heating and temperature limitation. These resistors
have a high conductivity at low temperatures, but at
a particular value known as the ʻCurie bendʼ, their
resistance increases considerably. This technology
allows automatic temperature limitation independently
of the supply voltage.
Economical use, compact, and protected against overheating.
According to VDE, CEE, UL, and CSA standards.
Their maximum surface temperature is lower than the ʻCurie
pointʼ, which is set according to the size of the device and the
prevalent heat-transfer conditions.
Connecting several PTC elements in parallel allows warm-up
time to be reduced without influencing the total power dissipated
at the regulation point.
