Product details

TF140DU are economical electromechanical motor protection devices for currents up to 142 A. In the event of overload, they provide reliable thermal protection for the connected motors. TF140DU are mounted on contactors AF116 to AF140. If the motor current set on the current scale is exceeded, the relays trigger via bimetallic elements, thereby changing the switching position of the two auxiliary contacts 1S/1Ö. A pre-connected contactor is then switched off. The relays allow for manual or automatic reset, and they feature a test and stop function as well as a triggered indicator. An additional reset button allows operation without opening the control cabinet. TF140DU have a tripping class of 10A, are temperature compensated, and are sensitive to phase failure.
