Siemens 3TF4010-0A Three-Phase Contactor 3-Pole

Siemens 3TF4010-0A is a three-pole AC-contactor from the 3TF4 motor-control family (catalog number 3TF4010-0A) designed to switch three-phase power. It provides three main contacts for AC-3 duty with a rated current of 9 A and is commonly found with a 120 V AC coil, as listed in retailer references for this model. This compact, three-pole contactor is used to start and stop small to mid-size three-phase motors and other three-phase loads in industrial panels, conveyors, pumps, and fans, aligning with Siemens’ documentation for the 3TF40 series and its variants, which include 110/120 V coil configurations for standard control voltages.
