Siemens 3RA2923‑2AA2 Wiring Kit (Spring‑Type) with Mechanical Interlock for Reversing Starter S0 Original Brand New

Overview: The Essential Reversing Starter Kit

The Siemens SIRIUS 3RA2923-2AA2 is an indispensable wiring kit designed for the fast, safe, and reliable construction of a reversing starter (reversing contactor assembly) in Size S0. This all-in-one kit eliminates complex manual wiring and ensures compliance with critical safety standards by providing both the necessary electrical and mechanical interlocking components. Featuring spring-type terminals, it guarantees a vibration-proof connection and significantly reduces installation time compared to traditional screw-type wiring.

Benefit

• Time-saving installation: Pre-configured wiring modules and interlock reduce assembly time and simplify wiring.

• Enhanced safety: Mechanical interlock ensures forward and reverse contactors cannot operate simultaneously, reducing risk of motor damage or electrical shorting.

• Reliable connections: Spring-type terminals ensure long-term, maintenance-free connections — no need to re-tighten screws.

• Compact design: Clip-on mounting saves space in control panels and maintains a clean, professional layout.

• Cost-efficiency: By using a single kit, you avoid sourcing multiple individual components; reduces inventory complexity.

• Standard compliance: Built to Siemens specifications and compatible with SIRIUS 3RA2 reversing starters.

Application

• Reversing motor starter assemblies (forward/reverse motor control)

• Industrial control panels

• Motor control centers (MCC) requiring compact, safe starter wiring

• Machinery maintenance and retrofit projects
