Pro-Therm Thermal Protector Characteristics

  Minimized Size : simply install and easy to design circuit and parts.
  Direct Sensing & Switching : install directly to heat generating parts and cut off immediately so easy to apply.
  High Speed Sensing : excellent heat reactivity and high reliable parts.
  Completely sealed : completely prevent from any moisture and humidity.
  Plastic(PBT)Case : high insulation.
  Low Cost : safe and high efficient parts at low cost.

* Possible to select various leads wire or bare wire.
* Wide Temperature Range: 45oC ~ 150oC

  Composition and function of parts


Bi-Metal Disc (6) sense temperature and make reverse turn to connect or disconnect contact
point.
Moving plate(Be-Cu) (5) elastic metal plate that open and close the contact point by rote related to
Bi-metal's reverse-turn.
Fixing plate(Brass) (4) metal plate that functions fixing plate of circuit unified to electric contact
point of fixing part.
Electric contact point
(Ag plated Cu)
(2,3)
consist of two fixing contact points and two moving contact parts and works
for connecting and disconnecting electric signal.
Insulator-1 (7) insulates between moving plate and fixing plate.
Insulator-2 (8) works as a electric insulation fixing the moving plate.
Wire & Lead (9) works as a media connecting electric circuit.
Cover(PBT) (1) sense the temperature and protect the internal components
Epoxy (10) fixing the case and internal electric circuit, sealing and insulating.
