Relevant applications:

Description

Oil boiler thermostat. 3-phase temperature regulation and bimetal safety limiter with manual reset

 

Features

  • Combined control and safety function
  • Multiple mounting
  • Factory pre-set fixed temperature, OEM adjustable or end-user adjustable temperature

 

Operation

A rise in temperature causes the expansion of liquid within the bulb and capillary. The liquid acts on a bellows assembly within the plastic housing to open and close electrical contacts with temperature variation. In case of abnormal rise in temperature, bimetal safety will break independent contacts to insure safety operation. The limiter is manually resettable.
