E.G.O. Germany (E.G.O. Elektro-Gerätebau GmbH)
document id.: 90.60145.653-001-02-A / state: 230 - released
designation: Thermostats 55.xxxxx.xxx / 56.xxxxx.xxx
Knob made of insulating material: Select at least 50 N pull-off forces in accordance with IEC 60335
part 1 ff.
2.3.4 Deformation
Mechanical deformations may lead to malfunctions or even destruction of the thermostat. The risk exists
particularly in the following cases:
Too long fastening screws
Crushing of the sensor
Kinking the capillary tube
Pull on the capillary tube
Effect of force and bending stress on the solder joint between sensor and capillary tube.
With adjustable thermostats: Deformation of the mechanics by exceeding the maximum stop torque
of 150 Ncm.
Observe the maximum screw-in depth of the fastening screws in the fastening bracket of the
thermostat (see type drawing).
Avoid mechanical effects on the sensor.
Never kink the capillary tube during assembly and operation (observe the minimum bending radius
according to the type drawing).
Do not exceed the tensile load of the capillary tube on the housing of 50 N.
With adjustable thermostats: Observe the maximum stop torque of 150 Ncm.
2.3.5 Ingress of foreign parts
Ingressing foreign parts can lead to malfunctions.
Install thermostats in a suitable housing protected from dust and moisture.
2.3.6 Too high force when attaching or removing the receptacle
The thermostat can be damaged due to excessive force when attaching or removing the socket.
When attaching and removing observe the instructions in accordance with the IEC 61210 standard
(axial forces for attaching and removing the blade terminal).
2.3.7 Too high force when putting on the knob
The thermostat can be damaged due to excessive force when attaching the knob.
Use a knob with a maximum push-on force of 50 N.
2.3.8 Incorrectly selected, assembled or reused stuffing box sets
Incorrectly selected, assembled or reused stuffing box sets can lead to leaks.
Select stuffing box sets according to the application. Pay particular attention to the temperature
resistance and maximum pressure resistance of the stuffing box seal.
Adhere to the specified tightening torque and the order of the individual parts during assembly so
that the capillary tube is not damaged.
Once installed, do not reuse the stuffing box sets after dismantling.
Test the tightness of the system through experiments.
