Siemens 3RT1954-6A Main Contact Replacement Kit 115A/600V for S6 Frame

Product Positioning

The 3RT1954-6A is a main contact replacement kit from Siemens' SIRIUS large contactor series, specifically designed for the 3RT1054 contactor with an S6 frame, AC-3 rating, and a capacity of 55kW. The kit contains 3 sets of movable contacts and 6 sets of fixed contacts, along with necessary installation parts, allowing for the complete replacement of the main contact assembly of a three-pole contactor. The biggest advantage of this type of spare part is that when the contactor experiences contact wear and arcing due to frequent and prolonged operation, it is not necessary to replace the entire contactor body; simply replacing the contact kit restores the original conduction and switching performance. This significantly reduces spare parts costs and downtime for the factory.

Core Product Advantages and Features

Complete contact group configuration

The kit provides 3 sets of movable contacts and 6 sets of fixed contacts, corresponding to the main circuit of a three-pole contactor, allowing you to purchase all the necessary parts for a complete replacement in one go.

Rated 115A/600V

It meets the rated current and voltage requirements of the 3RT1054 (S6 frame, AC-3 55kW) contactor, ensuring that the performance after replacement is consistent with the original.

Reduce maintenance costs

Compared to replacing the entire contactor, using contact kits for maintenance can effectively save on spare parts procurement and downtime costs, making it suitable for scheduled annual maintenance.

Original factory compatible design

The mounting structure and component dimensions are specifically designed for the 3RT1054, ensuring excellent installation compatibility and reducing rework caused by non-compliance during maintenance.
