Siemens 3TF56 02 Contactor is a three‑pole motor control device rated for 400 A at 600 V AC, designed for demanding industrial drives and equipment. It uses a 110/120 V AC coil and provides two normally open and two normally closed auxiliary contacts for signaling and interlocking in control circuits, enabling reliable start/stop and feedback without additional modules. With a 400 HP rating at 575 V and compatibility as a direct substitute for Siemens Sirius 3TF equipment, this contactor suits heavy‑duty motor applications such as pumps, conveyors, and processing lines in manufacturing settings.
