Product Positioning

The 3RT1966-4BA31 is a parallel swivel verbinder for Siemens SIRIUS large contactors. Its main function is to connect two identical 3RT1.6 or 3RT1.7 series contactors (S10 and S12 housings) in parallel, thereby expanding the current capacity of the main circuit. The verb features a three-pole design with through holes for easy securing with mounting screws. It is a crucial wiring accessory for handling high-current loads when parallel contactors are required.

Core Product Advantages and Features
Supports high-current parallel applications
Connecting two contactors of the same size in parallel is suitable for situations where the current rating of a single contactor is insufficient to handle the load.
Tri-polar integrated design
One piece covers the three-phase main circuit connection, eliminating the need to purchase individual single-pole parts separately, resulting in higher assembly efficiency.
With perforated fixing structure
The connecting piece itself is designed with perforations, which makes it easy to fix the position with screws and improve the mechanical strength of the joint.
Compatible with S10/S12 chassis
Designed specifically for the 3RT1.6 and 3RT1.7 series large contactors, with dimensions and hole positions conforming to the original factory standard.
