Product Description

Siemens 3RA2913-2AA1 Mechanical Interlock & Installation Kit for 3RT2 Reversing Contactors – S00-S00

The Siemens 3RA2913-2AA1 is an assembly kit for Siemens SIRIUS 3RT2 reversing contactor assemblies, designed for Size S00-S00 contactor arrangements. The kit includes the mechanical interlock, two connecting clips for two contactors, and wiring modules on the top and bottom for connecting the main, auxiliary and control circuits. Siemens specifies this version for screw-terminal contactors.

For SB Smart, this product is positioned as a Siemens industrial electrical accessory for supply, procurement, panel-building and replacement requirements, without claiming automation integration or automation-service work.

Siemens SIRIUS 3RA2913-2AA1 Assembly Kit

The 3RA2913-2AA1 belongs to the Siemens SIRIUS accessories used to create reversing contactor assemblies from compatible 3RT2 contactors.

A reversing starter normally uses two contactors so that a motor can be operated in forward and reverse directions. The assembly kit provides the mechanical and wiring components needed to arrange the two contactors as a coordinated reversing assembly.

Designed for S00-S00 Contactors

The exact 3RA2913-2AA1 is intended for S00-S00 reversing contactor arrangements. Siemens identifies the kit with 3RT201 contactors in the S00 size.

This makes it suitable for compact motor starters used in industrial electrical panels and machinery.

The exact 3RT2 contactor article numbers should be checked before ordering to ensure compatibility.

Mechanical Interlock Included

An important feature of the 3RA2913-2AA1 is that the mechanical interlock is included in the assembly kit.

The mechanical interlock physically prevents the two compatible contactors from being mechanically engaged simultaneously. This is particularly important in forward/reverse starter arrangements.

Siemens' documentation identifies the assembly kit as containing the mechanical interlock and two connecting clips for the two contactors.

Connecting Clips for Two Contactors

The kit includes two connecting clips for two contactors.

These clips help establish the required physical relationship between the two S00 contactors in the reversing assembly.

The standardized Siemens arrangement helps avoid the need for separately fabricated connection hardware when assembling compatible contactors.

Top and Bottom Wiring Modules

The 3RA2913-2AA1 also includes wiring modules at the top and bottom.

These modules are designed for connecting:

• Main circuits

• Auxiliary circuits

• Control circuits

Siemens identifies the kit as a complete assembly solution for making three-pole reversing contactor assemblies.

Screw-Terminal Version

The 3RA2913-2AA1 is the version intended for screw-terminal contactors.

Siemens lists 3RA2913-2AA2 as the corresponding spring-loaded-terminal version.

This distinction is important when selecting the correct accessory for the contactor terminal type.

Three-Pole Reversing Contactor Assembly

The exact kit is intended for making 3-pole contactor assemblies.

This configuration is suitable for three-phase motors requiring forward and reverse operation.

The standard arrangement uses one contactor for forward operation and the other for reverse operation, with the mechanical and electrical interlocking arranged to prevent an incorrect simultaneous switching condition.

Electrical Interlocking

The assembly kit provides wiring components for the control arrangement, while the complete contactor configuration can incorporate electrical interlocking through the appropriate auxiliary contacts.

Siemens documentation shows the reversing assembly with electrical interlock included in the wiring arrangement and the mechanical interlock as part of the kit.

The final control circuit should always be designed according to the applicable motor, machine and safety requirements.

Compatible 3RT201 Contactors

Siemens' current catalog identifies 3RA2913-2AA1 for 3RT201 S00-S00 reversing contactor assemblies.

The 3RT201 contactor family covers several motor-control ratings, so the exact contactor article should be selected according to the motor's rated power, current and control requirements.

Compact SIRIUS Assembly Solution

The 3RA2913-2AA1 provides several reversing-starter components within a single Siemens accessory article.

Instead of sourcing the mechanical interlock, contactor connectors and wiring modules separately, this assembly kit provides the specified components together for the supported S00-S00 configuration.

This can simplify:

• Procurement

• Panel assembly

• Replacement

• Maintenance

• Standardization of motor starters

Typical Applications

Forward/Reverse Motor Starters

The primary application is three-phase motor control where the motor must operate in both directions.

Machine Tools

Suitable for compatible machine-control assemblies requiring forward and reverse motor operation.

Conveyors

Useful for conveyor systems where controlled directional operation is required.

Material Handling Equipment

Suitable for compatible motor starters used in industrial material-handling equipment.

Production Machinery

Can be used in industrial machines requiring reversing motor control.

Electrical Control Panels

Panel builders can use the kit to create standardized Siemens S00 reversing contactor arrangements.

Suitable for OEMs, Panel Builders and Electrical Dealers

The 3RA2913-2AA1 is suitable for OEM equipment manufacturers, electrical panel builders, industrial maintenance teams, industrial buyers and electrical product dealers.

For SB Smart, this product should be positioned around industrial electrical product supply, dealer/distributor procurement and replacement sourcing, without claiming automation integration or automation-service work.
