Thermal Cutouts
Temperature Protection for Electronics
ADVANTAGES
– broad product range for many applications
and loads
– widest selection of connections and housings
– minimal contact resistance
E-Type
DESCRIPTION
Types E 05, E 11, E 15, E 16, E 18, E 21, E 22, E 23 and E 26 are
thermal cutouts.
Within limits they can also be used as temperatu-
re regulators.
A bimetal snap disc with single or double contact opens or closes an
electric circuit when reaching a pre-set temperature. Reset follows
after a substantial drop in temperature.
Heat transfer from all sides results from heat conduction or radiation
onto the base of the housing.
Standard version: aluminium, black anodised.

RESPONSE TEMPERATURES
When selecting the response temperature, the hea-
ting and cooling characteristics of the housing
should be considered. Temperature testing is carried
out with a rate of rise 0.1 °C/min.
For cutout types E 05, E 11 and E 18 with response
temperatures under 71 °C, the published electrical
loading should be reduced by upto 50 %, as these
types are current sensitive.
Close tolerances on the response temperature or
reset temperature, as well as smaller differentials
are all possible on request.
Reset differential as standard is between 10 °C and
50 °C. Minimum rate of temperature change 0.1
K/min.

INSTALLATION HINTS
It is important to ensure good heat transfer to the cu-
tout: it should be placed directly onto the heat sour-
ce.
Housings are voltage-free (except G 800) and can
be installed without additional insulation.
The cutouts can be attached to metal surfaces or
housings and, depending on the exact version, can
be screwed, clipped, clamed or soldered on.
G 800 version can be positioned direct onto a circuit
board.
