Smarty Plus NC
High Temperature Regulator
Tmax 360°C incl. Tolerance / Imax 12A / 230VAC / orientation independent mounting / temperature resistant ceramic housing / standard terminals
Properly installed, the high temperature regulator type 161 481 may be used for example in electric ranges and where a fixed temperature needs to be controlled.
A vaulted bimetal disc is used as the temperature sensing element. The disc is placed in direct contact with the thermostat mounting plate therefore reacting quickly to changes in temperature. Upon reaching the preset temperature the bimetal disc operates and opens the electrical contacts. After the coding phase, the disc snaps back into its original position thereby closing the circuit again. The higher sides of the insulator and the tab connector’s overlapping end with its fixed contact are providing an extensive protection against contacting the spring. The high temperature regulator type161 481 is also available with a ceramic cover.

Applications
Properly installed, the high temperature regulator type 161 481 may be used for example in electric ranges and where a fixed temperature needs to be controlled.
Structure and mode of operation
A vaulted bimetal disc is used as the temperature sensing element. The disc is placed in direct contact with the thermostat mounting plate therefore reacting quickly to changes in temperature. Upon reaching the preset temperature the bimetal disc operates and opens the electrical contacts. After the coding phase, the disc snaps back into its original position thereby closing the circuit again. The higher sides of the insulator and the tab connector’s overlapping end with its fixed contact are providing an extensive protection against contacting the spring. The high temperature regulator type161 481 is also available with a ceramic cover.
Advantages
- suitable for temperatures up to 360°C max.
- rapid heat transfer and short reaction time
- location independence and unchanged reaction time in all mounting positions
- simple, quick and safe installation with standard flange
- plug-in and welded connections for a safe an connection technology
- safe switching thanks to a high contact opening force
- rolling movement of the contacts
- long service life
