Siemens 3TF4011-0AK6 Contactor

The Siemens 3TF4011-0AK6 is an electromechanical AC contactor within the 3TF40 series, characterized by a maximum load current of 9 A under utilization category AC-3 for squirrel cage motor applications. Electromagnetic actuation occurs via a 230 V AC coil rated for 50 Hz and 60 Hz operating frequencies, facilitating deployment across global regions with differing grid standards. Auxiliary contact blocks are integrated to convey status signals, permitting the integration of motor control logic into broader electrical systems. The assembly accepts standard DIN rail mounting procedures, allowing installation next to disconnect switches or other protective devices within industrial cabinet spaces.
