SIRIUS 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 (PTC)
that are directly installed in the motor winding and abruptly
change their resistance at their limit temperature.

■ Benefits
• Thanks to direct motor protection, overdimensioning of the
motors is not necessary
• No settings on the device are necessary
• Solid-state compatible output thanks to versions with hard
gold-plated contacts

• Rapid error diagnosis thanks to versions that indicate openand short-circuit in the sensor circuit
• All versions with removable terminals
• All versions with screw terminals or alternatively with innovative spring-type terminals

■ Application
Direct motor protection through temperature monitoring of the
motor winding offers 100 % motor protection even under the
most difficult ambient conditions, without the need to make adjustments on the device. Versions with hard gold-plated contacts
ensure, in addition, a high switching reliability that is even higher
than an electronic control.

Stalling of the rotor

EN 60204 and IEC 60204 stipulate that motors must be protected from overheating at a rating of 0.5 kW and higher. The
protection can take the form of overload protection, overtemperature protection or current limiting.
For motors with frequent starting and braking and in environments where cooling may be impaired (e.g. by dust), it is recommended to use the overtemperature protection option in the form
of a protective device coordinated with this mode of operation.
A good choice in this case is the use of 3RN1 thermistor motor
protection devices.
On rotor-critical motors, overtemperature detection in the stator
windings can lead to delayed and hence inadequate protection.
In this case the standards stipulate additional protection, e.g. by
means of an overload relay.
This combination of thermistor motor protection and an overload
relay is recommended for full motor protection in case of frequent starting and braking of motors, irregular intermittent duty
or excessive switching frequency. To prevent premature tripping
of the overload relay in such operating conditions, a higher setting than that normally required for the operational current is chosen. The overload relay then performs the stall protection, and
the 3RN1 thermistor motor protection device monitors the temperature of the motor windings.

SIRIUS 3RN1 Thermistor Motor Protection
For PTC sensors
Use in areas subject to explosion hazard for gases

Note:

All devices are approved for Equipment Group II, Category (2)
in Area "G" (areas that contain explosive gases, vapor, spray and
air mixtures).

Tripping of the thermistor motor protection relay even in combination with a converter must directly result in disconnection. This
must be implemented with circuitry.

With PTB 01 ATEX 3218 ex II (2) G, compliance with directive
94/9 EC 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 used outside the area subject to explosion hazard.

Mounting and installation must only be performed by qualified
personnel who observe the applicable regulations! For mounting, use the mounting instructions
Order No.: 3ZX1012-0RN10-1AA1.

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 releases can be implemented
taking into account the safety notes. In the case of plants or machines with a high potential risk, versions with integrated shortcircuit detection in the sensor circuit are necessary.
Use in areas subject to explosion hazard for dust
PTB 01 ATEX 3218 ex II (2) GD
3RN10 11-.B/-.G, 3RN10 12-.B/-.G and 3RN10 13-...0 tripping
units can be used as protective 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 EC prototype test certificate which can be obtained from the Internet. The units comply
with the requirements of the following classes:
Device

EN 954-1: Category 2

For tripping units with a 24 V AC/DC control voltage, electrical
separation must be secured with a battery network or a safety
transformer to EN 61558.
When releases with Auto-RESET function are used, a reset is
performed automatically after the cooling time has expired. It
must be ensured by means of an external interlock (latching with
a separate ON and OFF button) that the machine to be monitored does not start up again spontaneously.
Units with the "Auto-RESET" function must not be used in applications in which the unexpected restart can lead to personal injury or property damage.
In the case of releases without short-circuit detection, during
commissioning or after modifications or maintenance work (assembly, disassembly) on the equipment, the sensor resistance
must be measured using a suitable measuring device. For resistances of < 50 Ω the sensor circuit must be checked for a
short-circuit.
If 3RN10 00 units are used to protect EEx e motors, separate
monitoring of the control voltage is recommended because there
is no Ready LED to indicate connection to the supply voltage.
If 3RN10 13-.BW01 unit are used to protect EEx e motors,
separate monitoring of the control voltage is recommended because the switching state of the auxiliary contacts does not
change if the control voltage fails (use of a bistable relay is
recommended).
Before commissioning, the effectiveness of the protection function must be checked.

The measuring circuit leads must be routed as separate control
cables. 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 cables must be used.

SIRIUS 3RN1 Thermistor Motor Protection
For PTC sensors
Principle of operation

3RN10 62 releases for multiple motor protection

The 3RN1 releases operate in accordance with the closed-circuit principle and therefore monitor themselves for open circuit
(except: warning output in the case of 3RN10 22). A momentary
voltage failure of less than 50 ms does not change the status of
the auxiliary contacts. The 3RN10 11, 3RN10 12 and 3RN10 13
units with 2 changeover contacts are also equipped with shortcircuit detection in the sensor circuit. The unit will trip in the event
of a short-circuit in the sensor circuit (resistance in sensor circuit
< 20 Ω).

Up to 6 sensor circuits can be connected to the 3RN10 62 release, all of which act on one output relay. The simultaneous protection of several motors (up to 6) is an advantage for multi-motor drives (e.g. if one motor is overloaded, all the other motors of
the drive will be shut down). Apart from the red LED "TRIPPED",
which signals the switching state of the release, a LED is assigned to each sensor circuit which indicates the sensor circuit
that has responded. Unused sensor circuits must be
short-circuited.

All tripping units (except for 24 V AC/DC) feature electrical separation between the control circuit and the sensor circuit.
3RN10 00 compact releases

The reset response of the 3RN10 62 releases can be changed
from Manual RESET to Auto-RESET by linking terminals Y1 and
Y2. Remote-RESET is implemented by connecting an external
pushbutton with a normally-open function.

The compact release is equipped with a red LED (TRIPPED) for
the tripped indicator and a changeover contact.

Response of the releases
in the event of control voltage failure

After the unit has tripped, it is automatically reset once the
thermistors have cooled down. The root of the changeover contact is connected to the control voltage (95 is connected to
terminal A1).
This unit is particularly suitable in circuits in which the control circuit and signaling circuit have the same potential, e.g. in local
control cabinets.

8

3RN10 10, 3RN10 11, 3RN10 12, 3RN10 13 standard releases
The standard devices are equipped with two LEDs (READY and
TRIPPED) for an operating and tripped display and are available
with either 1 NO + 1 NC or with 2 CO contacts. They are available
depending on the version with Auto-RESET (3RN10 10), Manual/Remote-RESET (3RN10 11) or Manual/Auto and RemoteRESET (3RN10 12 and 3RN10 13). Remote-RESET can be
achieved by connecting an external pushbutton with a normallyopen function to terminals Y1 and Y2. If terminals Y1 and Y2 are
bridged, tripping will be followed by an Auto-RESET.

The 3RN10 11, 3RN10 12 and 3RN10 13 units with 2 COs also
have short-circuit monitoring in the sensor circuit.
The 3RN10 12 and the 3RN10 13 are non-volatile. This means
that even if the control supply voltage fails, a trip preceding it will
be latched.
In the case of the 3RN10 13 release, tripping due to a short-circuit in the sensor circuit will be indicated by a flashing red LED.
The monostable version also indicates open circuit in the sensor
circuit by flashing of the red LED.
3RN10 22 "Warning and disconnection" releases
Two sensor circuits can be connected to one 3RN10 22 release
that acts on one output relay with 1 NO contact for warning and
1 CO for disconnection. Temperature sensors with different rated
response temperatures TNF are used to implement the "Warning" and "Disconnection" functions. When the "Warning" sensor
circuit responds, a yellow LED is lit and when the "Disconnection" circuit responds, a red LED is lit.
The sensor circuits have a different reset response and operating behavior:
• "Warning" (terminals 2T1, T2) only features Auto-RESET and
uses the open-circuit principle.
• "Disconnection" (terminals 1T1, T2) can be changed from
Manual RESET to Auto-RESET by linking terminals Y1 and Y2.
Remote-RESET is implemented by connecting an external
pushbutton with a normally-open function.
