Siemens 3RA2942-1A Busbar Adapter Size S3, Screw Mount for Circuit Breaker & Contactor Original Brand New

Overview

The Siemens 3RA2942-1A Busbar Adapter is a critical mounting accessory engineered for the flexible and secure mechanical installation of Size S3 circuit breakers and contactors. Designed as a robust plastic DIN rail adapter, it ensures stable integration into industrial control panels. This unit is part of the SIRIUS industrial control system, guaranteeing compatibility and top-tier performance for professionals requiring dependable electrical component mounting solutions.

Technical Specifications

• Product Number: 3RA2942-1A (or 3RA2942-1AA00 - if applicable, note both)
• Product Type: Busbar Adapter / DIN Rail Adapter
• Size Compatibility: Size S3 (for Circuit Breaker and Contactor)
• Material: High-quality Plastic
• Mounting Options: Snap-on mounting onto a standard 35 mm DIN rail OR Screw mounting for permanent fixation.
• Packaging: Multi-unit packaging (as per original description, or clarify if single unit)
• Key Application: Mechanical mounting of components onto busbar systems (typically in conjunction with other components).

Benefit and Application

• Simplified Installation: Offers dual mounting flexibility (snap-on or screw-fixed) for quick and adaptable panel assembly.
• Enhanced Stability: Provides a secure, mechanical base for heavy-duty Size S3 switching and protection devices, reducing vibration and ensuring longevity.
• Professional Integration: Seamlessly integrates Siemens SIRIUS 3RA2 contactors and circuit breakers, ensuring optimal system compatibility.
• Space & Time Savings: Facilitates organized, repeatable, and space-efficient assembly on the standard mounting rail or baseplate.

Function

The 3RA2942-1A functions as the intermediate mechanical link, enabling the installation of large Size S3 switching devices (like the 3RT2 contactor) directly onto a standard 35mm mounting rail or flat surface. This process is essential for creating robust, standardized, and easily maintainable load feeders or control gear combinations within an electrical enclosure.
