The Siemens 3RT1976-6D is a replacement contact set for the 3RT1476 contactor, containing three movable and six fixed contacts along with mounting hardware. Rated for use in Siemens contactors, this set restores the switching surfaces on worn units — a common intervention for high-cycle motor starters and power-switching circuits.
Integration Note
The 3RT1976-6D is designed exclusively for the 3RT1476 contactor frame. The kit includes both movable and fixed contacts plus the necessary mounting parts — no additional hardware needed. Replacement procedure follows standard contactor maintenance: isolate power, remove arc chute, swap contact pieces, and torque to manufacturer specifications.
