Product questions
What is the current setting range and trip class of the ABB T16-13?
ABB 1SAZ711201R1045 is the T16-13, with an adjustable overload setting of 10–13 A and trip class 10. Check the motor nameplate current and application requirements when selecting the relay.
Does the T16-13 protect against short circuits as well as overload?
The relay is intended to protect motors against overload and phase failure. ABB specifies that a separate short-circuit protective device is required; its selection depends on the circuit and applicable coordination requirements.
Does the T16-13 have manual and automatic reset and auxiliary contacts?
Yes. The reset mode is selectable between manual and automatic. The relay has a normally closed trip contact at 95–96 and a normally open signaling contact at 97–98.
How is the ABB T16-13 thermal overload relay mounted?
ABB describes direct mounting on specified mini or block contactors. A separate single-mounting kit allows mounting on a 35 mm DIN rail. Confirm the contactor model and equipment serial number before ordering for an existing assembly.
