Siemens 3tf2010-0bb4 Contactor Motor Control 10E

Siemens 3TF2010-0BB4 Contactor Motor Control, Size 00, is a three-pole motor starter designed for AC-3 switching of 3‑phase loads in control panels. It is rated for 400 V AC operation with a main current rating of 9 A (formatted to drive up to a 4 kW motor at 400 V), and is coil‑driven by 24 V DC with a coil power around 1.2 W for compact control wiring. The unit includes an auxiliary contact block 10E (1 NO) for control feedback or interlocking in the control circuit, while the main circuit provides three normally open contacts. Wiring uses screw terminals for reliability, and the assembly is compatible with 35 mm DIN rails via snap‑on mounting for quick installation in modular panels. This compact Size 00 contactor is well suited to motor-start applications in compact panels where space efficiency and integrated auxiliary contacts are advantageous.
