Definitions

  • the PTC element either a ceramic PTC element or a polymer PTC element may be used, but a polymer PTC element is preferably used.
  • the polymer PTC element is advantageous in that the resistance value of the element itself is lower than that of the ceramic PTC element and self-destruction is unlikely to occur even when the temperature exceeds a certain level.
  • the polymer PTC element has a lower voltage required to maintain the trip state than the ceramic PTC element, and can maintain the trip state even when the circuit voltage is low.
  • the contact can be maintained in an open state (latched state) and chattering phenomenon that repeatedly opens and closes the contact can be prevented.
  • the polymer PTC element is preferable in that it is smaller and has a lower resistance than the ceramic PTC element.
  • the arm portion 28 extends outward through the side surface of the resin housing 8.
  • the arm portion 28 is a portion for electrically connecting the protection element 1A of the present invention to a predetermined electric element, and performs the same function as the terminal.
  • a contact 58 may be provided on a portion 28 of the arm.
  • the PTC element 14 the second terminal 16
  • the insulating layer 18 the bimetal element 20
  • the arm 22 the upper plate 30, and the resin cover 6 are three-terminal type.
  • the configuration is substantially the same as the protection device 1A.
