Siemens 3RT2926-4NA00 Adapter for SIRIUS 3RT102 Traction Contactors, Auxiliary Switch Mounting Original Brand New

Overview

The Siemens 3RT2926-4NA00 is a specialized accessory designed for the SIRIUS industrial control system. It functions as an adapter plate, specifically engineered for the reliable mounting of auxiliary switch blocks. This adapter is essential for expanding the functionality and monitoring capabilities of particular traction contactors in the Siemens 3RT102 series. It ensures precise and secure mechanical coupling between the main contactor and the supplementary control components.

Key Features & Technical Detail

• Product Number (MLFB): 3RT2926-4NA00
• Manufacturer: Siemens (SIRIUS Industrial Controls)
• Product Type: Contactor Adapter / Accessory
• Compatibility (Contactor): Specifically for SIRIUS 3RT102.-.X.-0LA(0.2) traction contactors.
• Compatibility (Auxiliary Switch): Designed for mounting 3RH29..-…..-0MC0 auxiliary switches.
• Function: Enables the secure and modular attachment of auxiliary switch blocks to the specified traction contactors.
• Application: Used for signaling, interlocking, and status feedback in control circuits, particularly in applications requiring robust traction-grade components.
• Mounting: Simple and secure mechanical mounting (likely clip-on or screw-on), consistent with the SIRIUS modular system.

Benefit

• Enhanced Functionality: Allows for easy integration of additional monitoring and control contacts (auxiliary switches) onto the main power contactor.
• Seamless Compatibility: Guarantees a perfect fit and reliable connection for the specified Siemens 3RT102 traction contactors and 3RH29 auxiliary switches, eliminating compatibility concerns.
• System Integration (SIRIUS): Maintained modularity and consistency within the Siemens SIRIUS control system, simplifying installation, maintenance, and spare parts management.
• Reliability: Provides a secure and robust mounting platform, ensuring the auxiliary switch operates reliably in demanding industrial and traction environments.

Function

The 3RT2926-4NA00 serves as the bridge component between the main power contactor and the auxiliary switch block. In systems utilizing the 3RT102 traction contactor (with the specific suffix for traction applications), the standard mounting points for auxiliary switches may require this specific adapter for correct positioning and mechanical activation. It ensures that the movement of the main contactor’s armature is accurately transferred to the auxiliary switch contacts for reliable status indication or circuit logic.
