Product questions
What current range and trip class does ABB 1SAZ711201R1040 have?
The T16-7.6 has an adjustable overload setting range of 5.7–7.6 A and trip class 10. Check the motor nameplate and the complete protection design before selecting the relay.
What protection does the T16-7.6 provide, and does it replace short-circuit protection?
It provides thermal motor overload protection with phase-loss sensitivity. A separate, appropriately selected short-circuit protective device is required.
Does the T16-7.6 have manual and automatic reset?
Yes. Manual or automatic reset can be selected. The relay also has a trip indication, a stop function and one normally closed trip contact and one normally open signal contact.
Can this relay be mounted separately from a contactor?
A DB16 single mounting kit is offered for stand-alone mounting instead of direct contactor mounting. Check the mounting arrangement and the existing contactor model before ordering.
