Product questions
What current range and trip class does ABB 1SAZ421201R1003 have?
The TA200DU-135 has an adjustable current setting range of 100–135 A and a trip class of 10A. Check the motor current and starting requirements when selecting an overload relay.
What does the TA200DU-135 protect against, and how is it reset?
It is a thermal overload relay for motor protection against overload and phase failure. It has selectable manual or automatic reset, a trip indication, and STOP and TEST functions.
Can the TA200DU-135 be mounted separately from a contactor?
The relay connects directly to suitable block contactors; a separate single-mounting kit is also available as an accessory. Confirm the mounting arrangement and contactor model before ordering.
What auxiliary contacts and voltage ratings does the TA200DU-135 have?
It has one normally closed trip contact and one normally open signal contact. The listed operational voltage is 690 V AC for the main circuit and 500 V AC or 440 V DC for the auxiliary circuit; contact current ratings depend on the switching duty.
