3RA2923-3DA1
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.
Product Positioning
The 3RA2923-3DA1 is an upper-level wiring module for assembling Siemens SIRIUS S0 size forward and reverse contactors. It features a three-pole screw terminal design with the same phase, allowing for tight, gapless assembly of the contactors. This module is often paired with a corresponding lower-level module to form a complete forward and reverse starter structure.
Core Product Advantages and Features
Upper layer wiring module
It is a top wiring component in the assembly structure of a forward and reverse contactor, and is designed with the same phase.
Closely packed without gaps
Contactor assembly does not require maintaining gaps, resulting in a more compact structure.
Three-pole screw terminal
The three-pole design, combined with screw terminals, ensures a stable and reliable connection.
S0 size dedicated
Assembly requirements for Siemens SIRIUS S0 specification contactors.
Use with lower-level modules
It is often assembled with the 3RA2923-3EA1 lower module to form a complete starter.
