Description

Overview: Siemens 3RT1916-4BA31 Parallel Switching Link

The Siemens 3RT1916-4BA31 is a high-quality, 3-pole parallel switching link accessory designed specifically for the SIRIUS modular system. This connector is engineered for the parallel operation of two SIRIUS 3RT2.1 contactors (Size S00) that utilize screw terminals, simplifying the main circuit wiring and enhancing connection reliability. It provides a clean, terminal-less parallel connection, significantly reducing installation time and the potential for wiring errors.

• Manufacturer: Siemens
• Series: SIRIUS
• Product Designation: Parallel switching connection
• Contactor Compatibility: 3RT2.1 (Size S00) with screw terminal
• Poles: 3-pole
• Connection Type: Link for paralleling without connection terminal

Benefit

• Simplified Wiring: Eliminates the need for external wiring to achieve a parallel connection, leading to a much cleaner and more professional panel layout.
• Reduced Installation Time: Quick and easy screw fixing method allows for rapid integration into your contactor setup.
• High Reliability: Provides a secure, factory-designed connection, minimizing the risk of loose contacts or wiring faults in high-current applications.
• System Integration: Seamlessly integrates with the Siemens SIRIUS modular system, ensuring perfect fit and compatibility with 3RT2.1 contactors.
• Space-Saving: Its compact design, tailored for the Size S00 contactor, helps optimize control cabinet space.

Function & Application

The 3RT1916-4BA31 link is used to electrically parallel two 3RT2.1 contactors to increase the current carrying capacity for specific loads. By connecting the main power terminals of the two contactors together, it allows them to share the load.

• Function: Creates a reliable, 3-pole parallel electrical connection for the main power circuit of two contactors.
• Application: Ideal for applications requiring higher switching current than a single Size S00 contactor can handle, such as switching powerful motors or resistive loads.
