ABB TF65-67 O/L relay Nominal voltage: 690 V 1 maker Piece 1 pc(s)

TF65 are economical, electromechanical motor protection devices for currents up to 67 A. In case of overload, they offer reliable thermal protection of the connected motors. TF65 are normally mounted on contactors AF40 to AF65, but with the help of a stand-alone installation set, the devices can also be mounted separately on DIN rails. If the motor current set on the current scale is exceeded, the relays trigger via bimetal elements and thus change the switching position of the two auxiliary contacts 1S/1NC. An upstream contactor is then switched off. The relays allow manual or automatic resetting, they have a test and stop function as well as a trip display. The current scale of the devices can be sealed. Accessories such as reset buttons and steam reset buttons complete the range. TF65 have tripping class 10, are temperature compensated and phase failure sensitive and have an ATEX approval.
