Siemens 3TF48 22-0XK1 AC Contactor

Siemens 3TF4822-0XK1 is a three-pole AC contactor from the 3TF48 family, designed for motor control in three‑phase systems up to the common industrial line voltage (up to 500 V AC). This model uses an AC coil variant and is intended for AC‑3 duty, handling starts and stops of large three‑phase motors, pumps, blowers, and conveyors in industrial environments. It includes two normally open and two normally closed auxiliary contacts for signaling and control alongside the main power contacts, enabling interlocks and PLC control without extra hardware. The 3TF48 family is known for robust construction and compact footprint, with multiple coil configurations across the line; verified coil options include 110/120 VAC and 380 VAC, which allows integration with a wide range of control circuits. As a Siemens original equipment part, this specific 3TF4822-0XK1 variant is suitable for OEM installations and retrofit projects that require reliable switching of 3‑phase loads in demanding industrial settings.
