Product questions
What motor current range does the ABB E16DU-6.3 cover?
The overload setting range is 2.0–6.3 A. Check the motor nameplate current and the application requirements before selecting the relay; the current range alone does not establish suitability.
Does 1SAX111001R1104 need a separate power supply?
No. The E16DU-6.3 is self-supplied and does not need an additional external supply for the relay.
What protection and trip classes does this relay offer?
It is intended for motor overload and phase-failure protection. The trip class is selectable between 10E, 20E and 30E; the relay also has temperature compensation.
What reset options and auxiliary contacts are included?
The relay has selectable manual or automatic reset, one normally closed trip contact and one normally open signal contact. It also has stop and test functions and a trip indication.
