TF140DU-V1000 are economical, electromechanical motor protection devices for currents up to 142 A. In the event of an overload, they offer reliable thermal protection for the connected motors., TF140DU-V1000 are attached to contactors AF116 to AF140. If the motor current set on the current scale is exceeded, the relays are triggered via bimetal elements and thus change the switching position of the two auxiliary contacts 1S/1Ö. This switches off an upstream contactor. The relays allow manual or automatic resetting, they have a test and stop function and a triggered display. An add-on reset button allows operation without opening the control cabinet., TF140DU-V1000 have tripping class 10A, are temperature compensated and sensitive to phase failure and have ATEX approval.
