Product questions
What current range does the ABB E16DU-2.7 cover?
The exact-part specification lists an adjustable current range of 0.80–2.7 A. Another listing gives a 0.9 A lower limit, so verify the marking and current range on the actual unit before ordering.
Does 1SAX111001R1103 require a separate power supply?
No separate external supply is required: the E16DU-2.7 is a self-supplied electronic overload relay. It provides motor protection against overload and phase failure.
Which trip classes and reset options does the E16DU-2.7 offer?
The relay has selectable trip classes 10E, 20E and 30E, and a choice of manual or automatic reset. It also has STOP and TEST functions and a trip indication.
How is the E16DU-2.7 mounted and what contacts does it have?
The relay connects directly to a contactor; a separate mounting kit is also available. It has one normally closed trip contact and one normally open signal contact. Confirm the contactor model and equipment serial number before ordering for a specific installation.
What are the main and auxiliary circuit voltage ratings?
The listed rated operational voltage is 690 V AC for the main circuit and 600 V AC/DC for the auxiliary circuit. Check the complete circuit ratings and the application requirements before selection.
