Siemens 3TF44-22-OAK6 Three Phase Electrical Contactor

Siemens 3TF44-22-OAK6 is a three-pole AC contactor from the Siemens 3TF World Series, designed for reliable motor control in industrial applications. It handles three-phase loads up to 32 A at voltages up to 600 V AC and features two normally open and two normally closed auxiliary contacts for flexible control logic in start/stop circuits. The control coil is rated at 110/120 VAC and 60 Hz, allowing direct connection to standard AC control circuits. Compatible with Siemens Sirius type 3TF control systems, this unit is commonly used to switch motors, pumps, and fans in panels, conveyors, and other equipment where rugged, remote-operated switching is required. Typical horsepower ratings for this configuration are about 10 HP at 230 VAC, 25 HP at 460 VAC, and 30 HP at 575 VAC, depending on supply voltage. The 3-pole design and compact form factor make it suitable for integration into existing 3TF44 installations.
