Standards

IEC/EN 60947‑1,
IEC/EN 60947‑4‑1,
IEC/EN 60947‑5‑1 (auxiliary switches)

Ambient conditions

If the devices are used in ambient conditions which deviate from common industrial conditions (IEC 60721-3-3 "Stationary Use, Weather-Protected"), information must be obtained about possible restrictions with regard to the reliability and endurance of the device and possible protective measures. In this case contact our Technical Assistance,
Tel.: +49 (911) 895-5900
Email: technical-assistance@siemens.com.

Auxiliary contact complement
  • Size S00: an auxiliary contact is integrated in the basic device.
  • Sizes S0 to S3: The basic units contain two integrated auxiliary contacts (1 NO + 1 NC).
    All basic units, with the exception of coupling relays sizes S00 and S0, can be expanded using auxiliary switch blocks.
  • Sizes S6 to S12: These contactors are supplied with two laterally mounted auxiliary switch blocks. The fitting of auxiliary switches is possible on the front and on the side (the 3RT12 vacuum contactor is an exception: only lateral fitting of auxiliary switches is possible here).

For detailed information on the fitting of auxiliary switches, see the asset "Selection guide for mountable auxiliary switch blocks" under "Accessories and Spare Parts" → "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Contactor Relays" → "Auxiliary switch blocks" → "Instantaneous".

Contact reliability

If voltages ≤ 110 V and currents ≤ 100 mA are to be switched, the auxiliary contacts of the 3RT contactors or 3RH contactor relays should be used as they guarantee a high level of contact reliability.

These auxiliary contacts are especially suitable for solid-state circuits with currents ≥ 1 mA at a voltage of 17 V and higher.

Connection method

Main circuit

  • Sizes S00 and S0: screw or spring-type terminal, spring-type terminal with convenient plug-in design for device connectors
  • Sizes S2 and S3: screw terminals with box terminal; direct connection to the connecting bar possible with cable lugs for S3 when the box terminal is removed.
  • Sizes S6 to S12: screw terminals with connecting bars that the cables can be connected to using either cable lugs or flexible or rigid busbars. Alternatively, box terminals are available as accessories.

Auxiliary/control circuit

  • Sizes S00 to S12: Screw or spring-type terminals
Electromagnetic compatibility (EMC)

The 3RT contactors fulfill the requirements for environment category A.

Note:

When the contactors are used in an environment with frequency converters, the configuration notes in the Manual "SIRIUS – SIRIUS 3RT Contactors/Contactor Assemblies" must be observed, see topic "Technical specifications" → "More information".

Short-circuit protection

For short-circuit protection of the contactors without overload relay, see "Technical Specifications" of the relevant contactor.

Refer to the manuals for details of short-circuit protection of the contactors with overload relays; see topic "Technical specifications" → "More information".

Selection guides are available for the fuseless assembly of motor feeders consisting of a 3RV2 motor starter protector and a 3RT2 contactor, see "Load Feeders and Motor Starters" → "for Use in the Control Cabinet" → "3RA2 Load Feeders".

For the dimensioning of load feeders, see the following Configuration Manuals:

Motor protection

3RT2 contactors

3RU2 thermal overload relays or 3RB3 electronic overload relays can be fitted to the 3RT2 contactors for protection against overload. For overload relays, see "Protection devices".

3RT1 contactors

3RB2 electronic overload relays can be fitted to the 3RT1 contactors for protection against overload. For overload relays, see "Protection devices".

Plant and application monitoring

3RR2 monitoring relays can be fitted to the 3RT2 contactors for monitoring and measuring in the application. See "Monitoring and Control Devices" → "Relays" → "SIRIUS 3RR21, 3RR22 Monitoring Relays for Mounting on 3RT2 Contactors".

Ratings of three-phase motors

The quoted rating (in kW) refers to the output power on the motor shaft (according to the nameplate).

The power rating specifications of the contactors in kW (in accordance with IEC 60947-4-1, Table G) are guide values for 4-pole standard motors at 50 Hz AC and specified voltage (e.g. 400 V AC). The actual starting and rated data of the motor to be switched must be considered when selecting the units. The motor current, motor protection device and the permissible contactor current acc. to the utilization category must be aligned with each other.

Surge suppression

3RT contactors supplied without a coil circuit can be retrofitted with RC elements, varistors, diodes or diode assemblies (assembly of diode and Zener diode for short break times) for damping opening surges in the coil.

  • Size S00: the surge suppressors are plugged onto the front of the contactors here. Space is provided for them next to a snap-on auxiliary switch block.
  • Sizes S0 and S3: the surge suppressors can be plugged onto the front of the devices. In the case of size S3 contactors, surge suppressors can only be used as from product version E03.
  • Sizes S6 to S12: Replaceable operating mechanisms with integrated coil circuit (varistor)

Note:

The OFF-delay of the NO contact and the ON-delay of the NC contact are increased if the contactor coils are attenuated against voltage peaks (for details see the relevant manual → topic "Technical specifications" → "More information").

Contactors with voltage tap-off

The 3RT2 contactors in sizes S00 to S3 with voltage tap-off are special versions for mounting SIRIUS function modules for connection to the control system via IO‑Link or AS‑Interface. See "Accessories and Spare Parts" → "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Contactor Relays" → "Modules for Contactor Control".

Without a function module, the contactors can be used like the standard versions.

For more information on IO-Link and AS-Interface see "Industrial Communication".

Operating mechanism types

3RT2 contactors

3RT2 contactors are available as versions with conventional AC or DC operating mechanisms or as versions with a wide-range solid-state operating mechanism and a universal actuating voltage (AC or DC operation possible).

DC coupling contactors with reduced power consumption are also ideally suited for connection to the controller.

With an operating range between 0.8 to 1.1 x Us, control takes place via the control supply voltage connection A1 - A2 as is typically the case.

3RT1 contactors

The following control and/or actuator versions are available in sizes S6 to S12:

  • Conventional operating mechanisms
  • Solid-state operating mechanism
    Overvoltage damping of the operating mechanism coil is already integrated in the electronics for contactors with solid state operating mechanisms. The operating mechanisms are powered via a supply voltage with an operating range from 0.8 to 1.1 x Us, optionally also controlled depending on the chosen mode of operation. Alternatively, control is also possible via the separate 24 V DC control signal input. Various rated voltage ranges for AC/DC control are available.

    The following versions are available:
    • With two operating modes: Direct control or via CPU input
    • As above, but additionally with remaining lifetime indication (RLT)
    • With fail-safe PLC input for simplification of safety applications (without mode of operation selection)
Solenoid coils/drive units

3RT2 contactors

Coil replacement is possible for sizes S0 to S3.

3RT1 contactors

The operating mechanisms for 3RT10..-.A/-.N/-.P contactors are removable and can be replaced simply by unlocking and pulling them out.

IMPORTANT: Removal or changing of the operating mechanism is not permitted for 3RT10..-.S contactors with fail-safe control.

Safety applications

Contactors are a significant part of safety-related applications. They are generally the actuators that perform the switching operation leading to the safe disconnection of the corresponding application or system.

In addition to the provision of safety-related device data in the technical specifications and the Safety Evaluation Tool for the easy evaluation of the overall system, as well as accessories for simple and space-saving design, 3RT1 contactors that can be controlled directly by fail-safe controllers via fail-safe modules are also available in the high power range from 55 kW upwards.

For more information on safety systems, see "Safety systems".

Contactors for special applications
  • SIRIUS 3RT.4 contactors for resistive loads (AC-1), 3-pole, see "Switching Devices" → "Contactors and Contactor Assemblies" → "Contactors for Special Applications"
  • SIRIUS 3RT20 and 3RT10 contactors with an extended operating range, 3-pole (for rail applications), see "Switching Devices" → "Contactors and Contactor Assemblies" → "Contactors for Special Applications"
