Product questions
What current range and trip class does ABB 1SAZ421201R1004 have?
The TA200DU-150 has an adjustable current setting range of 110–150 A and trip class 10A. Check the motor nameplate current and application requirements when selecting an overload relay.
What protection and reset functions does the TA200DU-150 provide?
This three-pole thermal overload relay provides motor overload and phase-failure protection. It offers selectable manual or automatic reset, temperature compensation, a trip indicator, and test and stop functions.
Is 1SAZ421201R1004 the same as the TA200DU-150-V1000?
No. ABB identifies 1SAZ421201R1004 as TA200DU-150; its catalogue lists the V1000 variant under a different order code. Verify the exact reference and application requirements before ordering.
What are the voltage ratings and enclosure protection for this overload relay?
The listed main-circuit operational voltage is 690 V AC; auxiliary-circuit ratings are 500 V AC and 440 V DC. The housing is IP20, but the main-circuit terminals are IP00.
