Siemens 3TF3200-0B Contactor

Siemens 3TF3200-0B Contactor is a three-pole power device with a 24 V DC control coil, designed for AC-3 motor control duty. The main circuit is rated to switch up to 30 A at voltages up to 690 VAC (660–690 VAC range), making it suitable for three-phase motors, pumps, compressors, and other inductive loads in control panels and industrial automation. As part of Siemens’ Sicop family, the 3TF3200-0B offers robust, reliable operation for frequent switching in harsh industrial environments, while keeping coil actuation simple from a low-voltage DC control signal. This model enables straightforward on/off control of a three-phase load from a 24 V DC control circuit, aligning with common IEC wiring practices in manufacturing lines, conveyors, HVAC equipment, and processing machinery. The 3TF3200-0B variant is intended for installations that require a standard, compact contactor with a DC coil, providing predictable performance and compatibility with typical auxiliary components and mounting configurations within Siemens’ legacy contactor line.
