3RA2911-1C

Description

Overview

The Siemens 3RA2911-1C Spacer Disc is an essential mounting accessory for the SIRIUS 3RA2 modular system, specifically designed for use with the standard mounting rail adapter. This genuine Siemens component ensures the correct spacing between devices when mounting multiple units, particularly when installing 3RA2 load feeders or motor starter protectors on a DIN rail (standard mounting rail). It is supplied in multi-unit packaging (typically a minimum order quantity of 5) for cost-effective bulk installation in industrial control panels and machinery. This part guarantees compatibility and reliability within the SIRIUS modular control system.

Key Benefit

• Optimal Device Spacing: Ensures the required clearance and proper thermal dissipation between adjacent 3RA2 devices mounted on the adapter.
• System Integrity: Guarantees full compatibility and mechanical stability with the Siemens SIRIUS 3RA2 modular system.
• Simplified Installation: Facilitates fast and secure installation on the standard mounting rail adapter, reducing assembly time.
• Bulk Packaging: Available in multi-unit packaging for large-scale industrial projects and inventory efficiency.
• Genuine Quality: Original Siemens component with a long product lifecycle, assuring durability and compliance (RoHS compliant).

Technical Function & Application

The 3RA2911-1C spacer disc is a specialized mounting accessory used in electrical control applications.

• Function: It is installed onto the standard mounting rail adapter (also known as the DIN rail adapter) to maintain a precise, non-conductive mechanical separation between SIRIUS 3RA2 switching devices, such as the 3RV2 motor starter protectors and 3RT2 contactors. This is vital for safety, wiring accessibility, and maintaining the operational integrity of the entire load feeder assembly.
• Application: Primarily used in Industrial Control Panels, Motor Control Centers (MCCs), and Automation Systems where SIRIUS 3RA2 load feeders are utilized for switching and protecting electric motors.
