Siemens 3RA1954-2A SIRIUS Accessory — SIRIUS wiring/link module

The Siemens 3RA1954-2A is a genuine SIRIUS accessory: SIRIUS wiring/link module for 3RA contactor assemblies. It is supplied in Saudi Arabia by Razz Middle East to support reliable installation, expansion and protection of Siemens motor control assemblies across the Kingdom's industrial facilities.

Technical Overview

As part of the SIRIUS modular system, the 3RA1954-2A clips onto its companion devices through the standardised accessory interface, requiring no additional wiring or panel space beyond the host component. It is manufactured to the relevant IEC 60947 standards and matched precisely to the mechanical and electrical characteristics of its parent contactor, relay or circuit-breaker series.

Performance & Specifications

Using genuine Siemens accessories preserves the type-tested performance, coordination and warranty status of the complete assembly. The 3RA1954-2A is rated for the same -25 °C to +60 °C ambient range as the SIRIUS host devices and retains the IP20 finger-safe construction of the system. Because it is dimensioned to the exact frame of its parent series, it adds its function — be that auxiliary signalling, surge suppression or mechanical mounting — without enlarging the device footprint or compromising the clearance and creepage distances that underpin the assembly's voltage withstand. This matters in Saudi switchrooms, where high ambient temperature and dust ingress make verified accessory coordination an important factor in long-term reliability. Non-genuine substitutes frequently differ in contact metallurgy, suppression characteristics or mechanical tolerance, any of which can degrade switching reliability or invalidate the type-tested rating of the parent contactor, relay or circuit breaker.

Applications in Saudi Arabia

The 3RA1954-2A is used wherever its parent SIRIUS devices are deployed in Saudi Arabia — in motor control centres and control panels at SABIC and Sadara petrochemical plants in Jubail, NWC and SWCC water stations, MAADEN mining sites and ARAMCO utilities — adding signalling, surge protection or mounting functions to keep assemblies compliant and reliable.

Installation & Integration

The 3RA1954-2A fits its host SIRIUS device through the standardised front or lateral accessory interface without tools beyond a screwdriver, adding its function to the assembly while keeping the original footprint. Because it is dimensionally and electrically matched to the parent series, there is no need for separate mounting space, brackets or additional wiring runs. Razz Middle East stocks the full family of compatible SIRIUS accessories so customers can complete and document their Siemens assemblies from a single supplier in the Kingdom.

Standards, Quality & Compliance

Every 3RA1954-2A supplied by Razz Middle East is a genuine Siemens product, manufactured under ISO 9001 quality management and conforming to the relevant IEC 60947 standards with international CE and UL approvals. Sourcing through an authorized channel guarantees correct datecodes, factory documentation and full warranty cover — a critical safeguard on safety-related motor control and protection equipment, where counterfeit components present a real risk to plant and personnel. For ARAMCO, SABIC, MAADEN, NWC and NEOM contractors operating under strict approved-vendor and traceability regimes, this assurance shortens technical and commercial evaluation and keeps projects on schedule. Razz Middle East backs each delivery with selection support, cross-referencing from competitor part numbers and documented lead times.
