Product questions
What current range and trip class does ABB 1SAZ711201R1043 have?
The T16-10 has an adjustable overload current setting of 7.6–10 A and trip class 10. Check the motor nameplate current and starting conditions when selecting a relay.
What protection does the T16-10 provide, and does it replace short-circuit protection?
The relay provides motor overload and phase-failure protection. It is an overload relay, not a substitute for correctly selected short-circuit protection; verify the protective device and coordination for the installation.
Which contactors can the T16-10 mount on?
Published suitable contactors include ABB B6, BC6, B7, BC7, VB6, VBC6, VB7, VBC7, AS09, AS12 and AS16. A separate single-mounting kit is also available. Confirm the exact contactor and equipment details before ordering.
Does the T16-10 have manual reset and auxiliary contacts?
Yes. Manual or automatic reset is selectable. The relay has one normally closed trip contact and one normally open signal contact, plus a trip indication and STOP function.
