Mechanical thermostat

FZK 011

The set value corresponds to the upper switching point, here the normally closed contact opens. The set value minus the switching temperature differential of 5 K (and tolerances) corresponds to the lower switching point, here the normally closed contact closes. The mechanical thermostat is used to control heating, cooling devices, filter fans or signal transmitters.

Adjustable temperature
Small hysteresis enables precise control
High switching capacity
Changeover contact (heating or cooling)
Clip mounting

Note	The controller's contact system is exposed to environmental influences, which can change the contact resistance. This can lead to a voltage drop and/or self-heating of the contacts. During usage of the NC (normally closed) contact, there is the possibility of thermal return to reduce the switching temperature differential by connecting the clamp "N" (RF heating resistor). It depends on the ambient conditions and must be determined in tests for the respective application. Wire end ferrules must be used for connections with stranded wires.
