Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

1.1
Responsibility of the user for system configuration and functionality
The SIRIUS modular system offers various switching devices for the safe and functional
switching of electrical loads. 3RT2 contactors are available in sizes S00 to S3.
3RT1 contactors are available in sizes S6 to S12.
●3RT.0 power contactors and 3RT12 vacuum contactors for switching motorized loads
●4-pole 3RT23 contactors for switching resistive loads
●3-pole 3RT24 / 3RT14 contactors for switching resistive loads
●4-pole 3RT25 contactors for changing the polarity of hoisting gear motors
●3RH2 contactor relays for switching in the control circuit
●3RT26 capacitor contactors for switching capacitive loads (AC-6b)
●3RT1 / 3RT2 / 3RH2 contactors with extended operating range
–3RT10 / 3RT20 / 3RH21 contactors for rail applications
–3RT20 / 3RH21 coupling relays for system-compliant interaction with electronic
controllers
●3RT1...-.S.36 contactors with fail-safe control inputs for safety-related applications
●Operation of a motor in two directions of rotation (reversing contactor assembly)
●Starting three-phase motors with reduced starting current peaks (contactor assemblies for
star-delta (wye-delta) start)

1.3
Advantages through energy efficiency
Siemens offers you a unique portfolio for efficient energy management in industry – a
process that serves to optimally shape your energy requirement. Operational energy
management is subdivided into three phases:
●Identification
●Evaluation
●Realization
Siemens supports you with suitable hardware and software solutions in every phase of a
project.
More information can be found on the Internet
(http://www.automation.siemens.com/mcms/industrial-controls/en/energy-efficiency).
3RT contactors make the following contribution to energy efficiency in the overall plant:
●AC/DC coils with electrical control to reduce the closing power and holding power
●Smaller power supplies in the control circuit through low holding power at 24 V DC
●Reduced energy requirements of the contactors thanks to increased switching capacity in
each size from S00 to S3
Figure 1-1 Overview of the energy management process

Required basic knowledge
To understand these operating instructions you should have a general knowledge of
automation engineering and low-voltage switchgear.
1.5
Scope of the manual
The manual is valid for these contactors and contactor assemblies. It contains a description
of the devices that is valid at the time of publication.
