Product Positioning

The 3RT1966-6A is an original equipment manufacturer (OEM) service contact set provided by Siemens for the SIRIUS 3RT1066 large power contactor. It is designed to restore conductivity without replacing the entire contactor when the main circuit contacts suffer from burning or wear due to prolonged switching. The set includes 3 sets of movable contacts and 6 sets of fixed contacts, along with the necessary springs and mounting components. It is compatible with the same size (S10) housing as the 3RT1065/3RT1066 and features a 265A/AC-3/600V main circuit design, making it a practical spare part for extending the service life of large contactors.

Core Product Advantages and Features
Original factory compatible specifications
Designed specifically for the main circuit of SIRIUS 3RT1066 (S10 housing, AC-3 265A/600V rating) contactor, its dimensions and conductivity characteristics fully conform to the original manufacturer's standards.
A complete combination of three dynamic and six static elements.
With 3 sets of movable contacts and 6 sets of fixed contacts prepared at once, the three-pole main circuit can be replaced in one go, without having to piece together parts one by one.
Complete assembly parts included
The assembly includes contact springs and fixing screws, so no additional parts need to be found when replacing it on site.
Extend lifespan rather than replace it
When the contactor body is still intact and only the contact surfaces are burned and worn, replacing this component can restore its switching performance, which is more cost-effective than replacing the entire unit.
