Temperaturregler "Smarty Plus" Typ 161 571

Type 161 571

Thermostat "Smarty Plus" (normally closed)

The thermostat 161 571 is suitable for controlling or monitoring a fixed temperature. On request the thermostat is also available with increased differential (approx. 25-50 K). Typical applications are e.g. electric convection heaters.

A bimetal disc is used as a temperature sensing element. The disc is pressed directly against the mounting plate and can therefore react quickly to changes in temperature. As soon as the preset temperature is reached, the bimetal disc operates and opens the electrical contacts. On cooling the disc snaps back into the original position, closing the circuit again.

The thermostat version 161 571.9 is specially designed for low current ratings up to 1A (special contacts). The version 161 571.7 has an increased differential.

The thermostat is also available with a snap-on plastic cover. For high switch-off temperatures a ceramic cover with a clip can be used.
