Product questions
What is the current setting range of ABB 1SAZ411201R2001?
The published technical data lists 65–90 A, but another exact-part listing gives 66–90 A. Confirm the lower limit with ABB before selecting the relay for a motor near 65–66 A.
What trip class and auxiliary contacts does the TA110DU-90M have?
The TA110DU-90M is listed as trip class 10A and has one normally open and one normally closed auxiliary contact. Check the contact ratings against the control circuit.
What circuit voltage and enclosure protection ratings are listed for this relay?
The published ratings include 690 V AC for the main circuit and 690 V rated insulation voltage. The housing is IP20, while the main circuit terminals are IP10; these are different protection ratings.
What should I check before replacing an overload relay with the TA110DU-90M?
Compare the motor nameplate current, circuit voltage, trip class, contact arrangement and physical dimensions with the existing installation. The available data does not establish fitment for a particular machine; provide its model and serial number and the contactor part number for verification.
