3RN1 Thermistor Motor Protection
For PTC sensors
Overview
Thermistor motor protection devices are used for direct
monitoring of the motor winding temperature. For this purpose,
the motors are equipped with temperature-dependent resistors
Design
The 3RN1 tripping units are suitable for use in any climate and
finger-safe according to EN 0106 Part 50274. They comply with:
• EN 61000-6-2 and EN 61000-6-4, "Electromagnetic
• EN 60947-8
The terminals of the auxiliary contacts are designated in
accordance with EN 50005.
The 3RN1 tripping units are suitable for snap-on mounting onto
35 mm standard mounting rails according to EN 50022 or for
screw-mounting using an adapter (Accessories).
Any mounting position is possible.
For devices with the "Manual RESET" function, the test function
can be activated and a trip simulated by pressing the blue
Test/RESET button for longer than 2 seconds.
If a Type A temperature sensor is connected to a Type A tripping
unit, compliance with the operating temperatures is assured (on
pick-up and reset) according to IEC 60034-11-2 (EN 60947-8).
The characteristic curves of the Type A temperature sensors are
described in EN 60947-8, DIN 44081 and DIN 44082.

Use in areas subject to explosion hazard for gases
All devices are approved for Equipment Group II, Category (2)
in Area "G" (areas that contain explosive gases, vapor, spray and
air mixtures).
With PTB 01 ATEX 3218 ex II (2) G, compliance with
guideline 94/9 EG Appendix II is confirmed. The safety devices
must be selected with suitable settings for the safe operation of
motors of the "Increased safety" (EEx e) and "Flameproof
enclosure" (EEx d) degrees of protection and are accessed
outside the area subject to explosion hazard.
PTB 01 ATEX 3218 ex II (2) G
The increased danger in areas subject to explosion hazard
demands careful analysis of the operator's guide, the safety and
commissioning instructions and the standard (EN 60079-14/
VDE 0165) for electronic equipment in areas subject to gas
explosion hazards.
A risk analysis must be performed for the complete plant or
machine. If this risk analysis results in a minimal potential for
danger (Safety Category 1), all 3RN1 TMS tripping units can be
implemented taking into account the safety notes. In the case of
plants or machines with a high potential risk, variants with
integrated short-circuit detection in the sensor circuit are
necessary.
Use in areas subject to explosion hazard for dust
PTB 01 ATEX 3218 ex II (2) G
3RN10 11-.B/-.G, 3RN10 12-.B/-.G and 3RN10 13-...0 tripping
units can be used as safety devices for motors in areas subject
to gas explosion hazard for protection against impermissible
overheating due to overload. If the ATEX marking has the
extension "D:=Dust", these units can also be used as protective
devices for motors in areas subject to dust explosion hazard
(EN 50281-1-1).
Additional information is provided in the EU type test certificate
which can be obtained from the Internet. The units comply with
the requirements of the following classes:
The measuring circuit leads must be routed as separate control
leads. It is not permitted to use cores from the supply line of the
motor or any other main supply cables. If extreme inductive or
capacitive interference is expected as a result of power lines
routed in parallel, shielded control leads must be used.
