Siemens AG 3TF3400-0AP61 Three-Phase Contactor

Siemens AG 3TF3400-0AP61 is a three-pole power contactor in the SICOP 3TF family with a 220 V coil, designed for switching three-phase circuits in industrial control panels. It enables reliable on/off control of AC motors and other inductive loads in manufacturing and automation environments, delivering robust switching performance in a compact footprint. As part of Siemens' 3TF lineup, this device supports standard three-phase control applications where a 220 V control voltage is available and modular integration with auxiliary contacts and mounting configurations is required. The 220 V coil specification aligns with common plant control-power architectures, making it suitable for inclusion in motor starters, conveyors, pumps, and fans within an automation project.
