Siemens 3TY7460 Contact Kit

Siemens 3TY7460-0A is a replacement main contact kit for the Siemens 3TF46 three-pole power contactor (Size 6), engineered to refurbish the primary switching path without requiring a full replacement of the contactor assembly, thereby preserving original electrical characteristics and minimizing downtime during maintenance. The kit comprises 3 moving main contacts and 6 fixed contacts, precisely matched to the 3TF46 contact arrangement to restore current-carrying capacity, arc endurance, and switching reliability across all three poles after wear or pitting of the original components. Catalog entries identify this part as a SICOP main contact kit for the 3TF46, with some listings showing an alternate variant code 3TY7460-0YA and a 45 A rating, signaling its suitability for mid-range industrial circuits and equipment that operate within those current ranges. Designed specifically for use with the 3TF46 contactor, the 3TY7460-0A/0YA kit serves as Siemens’ official spare-part option for legacy equipment, enabling technicians to perform component refurbishment within control panels that rely on Siemens legacy IEC equipment.
