The 3RA2926-1A is a Siemens SIRIUS series S0 size safety main circuit connector with a three-prong screw terminal design. Its main purpose is to connect two S0 size 3RT20 contactors in series. It is commonly used in motor control circuits that require safety redundancy and is an important component in the assembly of safety-related starters.

3RA2923-3EA1 is a bottom part of the Siemens SIRIUS S0 size forward and reverse contactor assembly line module. It adopts a screw terminal design, and the contactors can be tightly arranged and assembled without leaving gaps. It is often paired with the corresponding upper module to form a complete forward and reverse starter. Each package contains five pieces.

The 3RA2923-3DA1 is the top component of the Siemens SIRIUS S0 size forward and reverse contactor assembly line module. It adopts the same phase and three-pole screw terminal design, and the contactors can be assembled in a tight arrangement without gaps. It is often paired with the lower module 3RA2923-3EA1 to form a complete forward and reverse starter structure.

The 3RA2923-2BB1 is a Siemens SIRIUS S0 size star-delta wiring kit with built-in mechanical interlocking and screw terminal design. It helps to assemble S0 size contactors into a star-delta reduced voltage starting circuit, taking into account both electrical connection and mechanical safety interlocking. It is suitable for starting small three-phase motors.

The 3RA2923-2AA2 is a Siemens SIRIUS S0 size forward and reverse wiring kit. It features a spring-loaded terminal design and built-in mechanical interlock to help assemble two S0 size contactors into a forward and reverse control circuit. The spring-loaded terminals allow for screwless, quick wiring, and the mechanical interlock effectively prevents contactor malfunctions.

The 3RA2923-2AA1 is a Siemens SIRIUS 3RA29 series S0 specification interlocking wiring kit. It combines a mechanical interlocker, connecting clips, and upper and lower wiring modules, allowing for quick and easy connection of two 3RT202 contactors to form a forward/reverse motor starter.
