Product questions
What is the adjustable current range of ABB 1SAZ811201R1007?
The TF65-67 has an adjustable overload setting range of 57–67 A and a rated operational current of 67 A. Check the motor nameplate current and the overall protection design before selecting the relay.
What protection does the TF65-67 provide, and what is its trip class?
The TF65-67 is a thermal overload relay for motor overload and phase-failure protection. It has a class 10 trip characteristic; it should not be treated as a complete short-circuit protection device.
Does the TF65-67 have manual and automatic reset?
Yes. Manual or automatic reset can be selected. The relay also has a trip indication and a STOP function; select the reset mode appropriate to the machine’s safety design.
What auxiliary contacts are included with the TF65-67?
It has one normally closed trip contact and one normally open signal contact. Check the auxiliary circuit ratings against the control circuit before use.
Can the TF65-67 be mounted directly to an ABB contactor?
ABB TF65-67 is listed for direct connection to block contactors, with AF40, AF52 and AF65 listed as suitable. Confirm the exact contactor and installation details before ordering; provide the equipment model and serial number if machine fitment is uncertain.
