DESCRIPTION
PTC thermistors act as thermal protection for electrical machines, and
are well known particularly as motor-protectors. They are available with
or without insulating sleeve and have flexible connecting leads.
PTC thermistors have a non-linear resistance/temperature response,
and at a specified temperature the resistance changes rapidly to a very
high value.

- PTC’s are classified according to their nominal
response temperature but all have similar
resistance characteristics to simplify the choice
of switching device; the relationship of resistance
to temperature of all these PTC’s is as follows:
OPERATION
NAT
PTC thermistors exhibit very high sensitivity over a
narrow temperature band. For temperature measure-
ment in this range, NTC thermistors are easier to
measure and more accurate.
STANDARD RESISTANCE VALUES

off through a relay or amplifier, since the PTC-sensor
will have an extremely high ohmic value in the region
of its response temperature. This will have the same
effect as a break in the circuit or a failure of the
thermistor.

SPECIAL VERSIONS
PTC’s are also available in many special housings
(can be manufactured to customers specifications)
Twin/double and triple PTC’s are available with

INSTALLATION TIPS
For PTC temperature sensors in electrical windings:
- the thermistors can only be inserted in the windings
before impregnation
QUALITY STANDARD
Random testing is carried out according to DGQ
P90/P10 (DIN 40080). AQL values can be fixed by
arrangement.
- it is advisable to embed one in each phase, if
possible in the centre of the coil generating most
heat, and generally on the outflow side of any air
movement
- air inflow onto the temperature sensor will interfere
with heat transfer
- if using varnish/lacquer which is not chemically
neutral, suitability tests must be undertaken by the
customer

- WARNING! It is very important that the sensor must
be installed parallel with the copper of the winding,
so that the teflon leads can assume the form of the
rest of the winding and thereby retain the high-
voltage resistance rating.

DESCRIPTION
PTC CONNECTION
These PTC relay units have been developed as state
of the art devices. All other commercially available
units can be replaced with ours.
Max. quantity of PTC connectable:
Terminal voltage for PTC’s
Range:
6 pcs
larger 1.6 k
Smaller 3.6 k +/- 10 %
Relay unit and sensors as per DIN 44081 and 44082
give optimum protection against thermal overload.
Together they provide a rapid and reliable motor-pro-
tection system.
SPECIAL VERSIONS
Two basic formats are available:
PTC sensors can be delivered with a warning label/
tag. This has a 4 cm cord, so that the tag can be seen
from the exterior when attached to the motor, equip-
ment or plant, and will warn against applying voltages
higher than 2.5V (surely this should be 2.5 kV).
TKA1 for applications where space is at a premium
TKA2 in a DIN housing, eg. for use in control panels
Any PTC thermistors that conform to DIN 44081 or
44082 can be connected to these relay units.
The ordering code for this label ist K105.
INSTALLATION
Screw or snap-on fixing TKA2
Installed on a 35 mm rail to DIN 46277 B.3 by means
of an integral snap-on housing.
