Overview

SIRIUS 3RN1 thermistor motor protection

Thermistor motor protection devices are used for direct monitor-

ing of the motor winding temperature. For this purpose, the mo-

tors are equipped with temperature-dependent resistors (PTC)

that are directly installed in the motor winding and abruptly

change their resistance at their limit temperature.

Order No. scheme

Note:

The Order No. scheme is presented here merely for information

purposes and for better understanding of the logic behind the

order numbers.

For your orders, please use the order numbers quote in the

catalog in the Selection and ordering data.

■

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 open-

and short-circuit in the sensor circuit

• All versions with removable terminals

• All versions with screw terminals or alternatively with innova-

tive 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 ad-

justments on the device. Versions with hard gold-plated contacts

ensure, in addition, a high switching reliability that is even higher

than an electronic control.

Direct motor protection

• At increased ambient temperatures

• For high switching frequency

• For long start-up and braking procedures

• Used together with frequency converters (low speeds)

ATEX approval for operation in areas subject to explosion

hazard

The SIRIUS 3RN1 thermistor motor protection relay for PTC sen-

sors is certified according to ATEX Ex II (2) G and GD for gases

and dust see www.siemens.com/industrial-controls/atex

SIRIUS 3RN1 Thermistor Motor Protection

For PTC sensors

8/104 Siemens IC 10 · 2011

Motor protection using current- and temperature-dependent

protective devices

EN 60204 and IEC 60204 stipulate that motors must be pro-

tected from overheating at a rating of 0.5 kW and higher. The

protection can take the form of overload protection, overtemper-

ature protection or current limiting.

For motors with frequent starting and braking and in environ-

ments where cooling may be impaired (e.g. by dust), it is recom-

mended 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 fre-

quent 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 set-

ting than that normally required for the operational current is cho-

sen. The overload relay then performs the stall protection, and

the 3RN1 thermistor motor protection device monitors the tem-

perature of the motor windings.

Siemens IC 10 · 2011

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 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 sub-

ject to explosion hazard.

PTB 01 ATEX 3218 ex II (2) G

The increased danger in areas subject to explosion hazard de-

mands 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 ex-

plosion hazards.

A risk analysis must be performed for the complete plant or ma-

chine. 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 ma-

chines with a high potential risk, versions 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) 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 sub-

ject to gas explosion hazard for protection against impermissible

overheating due to overload. If the ATEX marking has the exten-

sion "D:=Dust", these units can also be used as protective de-

vices for motors in areas subject to dust explosion hazard

(EN 50281-1-1).

Additional information is provided in the EC prototype test certif-

icate 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

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.

Cable routing

Maximum cable length for sensor circuit cables

A short-circuit in the sensor circuit will be detected up to this maximum

cable length.

Note:

Tripping of the thermistor motor protection relay even in combi-

nation with a converter must directly result in disconnection. This

must be implemented with circuitry.

Mounting and installation must only be performed by qualified

personnel who observe the applicable regulations! For mount-

ing, use the mounting instructions

Order No.: 3ZX1012-0RN10-1AA1.

The 3RN10 is not intended for installation in hazardous areas.

For installation in areas subject to explosion hazards, the 3RN10

must be enclosed in a flameproof casing.

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 moni-

tored does not start up again spontaneously.

Units with the "Auto-RESET" function must not be used in appli-

cations in which the unexpected restart can lead to personal in-

jury or property damage.

In the case of releases without short-circuit detection, during

commissioning or after modifications or maintenance work (as-

sembly, disassembly) on the equipment, the sensor resistance

must be measured using a suitable measuring device. For resis-

tances of < 50

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 be-

cause 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 func-

tion must be checked.

SIRIUS 3RN1 Thermistor Motor Protection

For PTC sensors

8/106 Siemens IC 10 · 2011

Principle of operation

The 3RN1 releases operate in accordance with the closed-cir-

cuit 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 short-

circuit 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).

All tripping units (except for 24 V AC/DC) feature electrical sep-

aration between the control circuit and the sensor circuit.

3RN10 00 compact releases

The compact release is equipped with a red LED (TRIPPED) for

the tripped indicator and a changeover contact.

After the unit has tripped, it is automatically reset once the

thermistors have cooled down. The root of the changeover con-

tact is connected to the control voltage (95 is connected to

terminal A1).

This unit is particularly suitable in circuits in which the control cir-

cuit and signaling circuit have the same potential, e.g. in local

control cabinets.

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), Man-

ual/Remote-RESET (3RN10 11) or Manual/Auto and Remote-

RESET (3RN10 12 and 3RN10 13). Remote-RESET can be

achieved by connecting an external pushbutton with a normally-

open 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-cir-

cuit 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 "Warn-

ing" and "Disconnection" functions. When the "Warning" sensor

circuit responds, a yellow LED is lit and when the "Disconnec-

tion" circuit responds, a red LED is lit.

The sensor circuits have a different reset response and operat-

ing 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.

3RN10 62 releases for multiple motor protection

Up to 6 sensor circuits can be connected to the 3RN10 62 re-

lease, all of which act on one output relay. The simultaneous pro-

tection of several motors (up to 6) is an advantage for multi-mo-

tor 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 as-

signed to each sensor circuit which indicates the sensor circuit

that has responded. Unused sensor circuits must be

short-circuited.

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.
