Product questions
What is the adjustable current range of ABB 1SAZ711201R1047?
The T16-16 has an adjustable overload setting range of 13–16 A and a class 10 trip characteristic. Check the motor nameplate current and the starter design before selecting the relay.
Does the T16-16 provide short-circuit protection?
The relay provides motor overload protection and is sensitive to phase failure. It requires separate short-circuit protection; the protective device must be selected for the complete installation and applicable requirements.
Does the T16-16 have manual and automatic reset?
Yes. Manual or automatic reset can be selected. The relay also has an NC trip contact, an NO signal contact and a trip indication. Assess whether automatic restarting is safe for the machine.
How is the T16-16 mounted?
The relay can mount directly to specified ABB mini or block contactors; a separate single-mounting kit is an alternative. Confirm the contactor model and equipment details, including serial number where applicable, before ordering.
