It contains 4 movable and 8 fixed main contacts — a 4 NO configuration — with all mounting parts needed for the swap. The AC-1 resistive rating of 140 A tells you the continuous current capacity when switching non-inductive loads like heaters or lighting banks; for motor duty (AC-3) the contactor itself carries a lower rating, but this kit restores the original contactor's full capability.","metaTitle":"Siemens 3RT1946-6E replacement contact pieces, 140 A AC-1, S","metaDescription":"Siemens 3RT1946-6E replacement contact set for Size S3 contactors: 4 NO main contacts, 140 A AC-1.
