Capillary thermal cutout KNTP 881*.**

Description

KNTP is built-in single pole disconnecting thermal cutout based on the principle of liquid dilatation. It consists from two basic parts: switching unit and capillary temperature sensor. If the surrounding temperature of sensor reaches the set disconnection temperature, the electrical circuit is disconnected. The circuit can be reconnected only manually by pressing the reset button after temperature sensor is cooled down. It is not allowed to turn on KNTP under electric load. Only knowledgeable person can reset KNTP 881*.**.

KNTP is installed with two M4 screws. There is a protective earth pin on the cover.

Advantages

  • variable location of temperature sensor in relation to position of switching unit
  • switching unit can be installed in any position
  • capillary can be bent according to installation need
  • no consumption of electrical power
  • low operating and servicing costs
