Siemens 3RT1946-4BB31 Paralleling Link, 3-Pole with Connecting Terminals for SIRIUS 3RT Series Original Brand New

Overview

The Siemens 3RT1946-4BB31 is a high-quality, factory-engineered accessory designed to enable safe and efficient paralleling of contactor modules in industrial control systems. Compatible with the SIRIUS modular system, this 3-pole paralleling link features connecting terminals and is engineered for seamless integration with Siemens 3RT2.4, 3RT104, and 3RT204 contactor ranges.
Manufactured in Germany and complying with RoHS regulations, this accessory supports reliable performance in electrical control cabinets and automation infrastructure.

Key Functions & Features

• 3-pole paralleling connection: Enables linking of three poles to allow parallel operation of multiple contactor modules in a synchronized arrangement.

• Connecting terminals included: Simplifies wiring and installation with pre-designed terminal blocks for fast, reliable connections.

• Designed for Siemens SIRIUS systems: Specifically tailored for integration with the SIRIUS 3RT2.4 series and 3RT104/3RT204 modules, supporting modular design and flexibility.

• High build quality & compliance: German origin, high manufacturing standards, RoHS compliant, suitable for industrial automation environments.

• Compact and efficient: Low-profile accessory that fits seamlessly within the control cabinet, facilitating neat wiring and minimal footprint.

Benefit

• Improved reliability: By enabling proper parallel wiring of contactor modules, this paralleling link ensures that each pole is reliably connected, reducing the risk of imbalanced loads or electrical faults.

• Faster installation: With designed terminals and compatibility built in, the accessory helps save time during wiring and commissioning.

• Scalable system design: Supports modular expansion, allowing you to link contactors in parallel for higher capacity or redundancy configurations without bespoke wiring solutions.

• Cleaner wiring layout: Helps maintain a tidy control panel—one standardized accessory, less custom wiring, better maintenance access.

• Brand assurance: Backed by Siemens’ reputation for industrial-automation components; spares and accessories from the same ecosystem yield better longevity and serviceability.

Application

• Industrial motor control centres where multiple contactors operate in parallel for large motors or banks of motors.

• Automation panels in manufacturing plants, processing lines, and equipment where redundancy or synchronized switching is required.

• Retrofitting or upgrading existing SIRIUS contactor installations with proper paralleling links to comply with standard wiring practices.

• Electrical distributors or panel builders specifying accessories for Siemens contactor modules within control cabinets or switchgear assemblies.
