130°C KSD302 250V 16A NC ceramic bi-metallic mechanical thermostat *new*

Water and steam heating systems have traditionally had overall control by bi-metallic strip thermostats. These sense the temperature using the differential expansion of two metals, which allows for precise contacts on/off switching. Typically the central system would be switched on when the temperature drops below the setpoint on the thermostat, and switched off when it rises above, with a few degrees of hysteresis to prevent excessive switching.

A bimetallic thermostat can be found in use:

• Electric convection heaters
• Amplifiers
• Coffee makers
• Water kettles
• Smoke machines
• Washing machines
• As an over temperature switch in electronics
• Generally where on/off type control is required

Thermostat technical details:

• Max operating voltage:
  • 250V
• Max operating current:
  • 16A AC
• Contact type:
  • NC (normally closed)
• Mode of operation:
  • Under nominal temperature:
    • Switch is closed (electricity flows through)
  • Over nominal temperature:
    • Switch is closed (electricity does not flow)
  • Switch does autoreset itself when it cool down sufficiently
• Nominal switching temperature:
  • 130°C
• Connector type:
  • 6,3x0,8mm flat blade connectors
• Installation method:
  • Screw mountable through 2x 3,3x5mm oval holes against potentially heating object
  • 23mm nominal hole spacing
• Overall height:
  • 21,5mm
• Construction:
  • Metal/ceramic which is capable in withstanding high temperatures way better than the plastic alternatives.
