Information

Overview Downloads Applications / Compatibility Product Precautions

ABB TA25DU-1.8M 1SAZ211201R2025 protects a compatible motor starter against sustained overload and phase failure through thermally operated bimetal elements.

Current adjustment: 1.30–1.80 A
Overload behavior: Trip class 10A
Auxiliary circuits: Separate 1 NO and 1 NC contacts

The three bimetal elements respond to motor-current heating and change the auxiliary contact states when the overload mechanism trips. The 1.30–1.80 A setting range must be matched to the motor and starter application, not simply set to the highest available value.

The 95–96 NC contact and 97–98 NO contact are electrically separate. Their functions in the contactor control and trip indication circuit must be checked independently, including the selected manual or automatic reset behavior.

The relay is phase-loss sensitive and temperature compensated within its specified ambient range. It requires coordination with the starter and short-circuit protective device; the thermal trip function does not replace short-circuit protection.

Controller platform reference: ABB TA25DU-M motor protection. Coordinate the relay with the motor, contactor and short-circuit protection.

The original technical excerpt applicable to ABB TA25DU-1.8M 1SAZ211201R2025 covers exact current range, utilization ratings and terminal data. The separate installation guide covers motor setting, contactor fit, terminal torque, trip and reset tests.

Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.

System and supply context: The relay forms part of a motor starter and operates its auxiliary control contacts when the thermal mechanism trips.

Application scope: Apply the exact 1.30–1.80 A range to the motor duty and preserve the coordinated starter circuit.

Small motor overload
Set thermal protection within the selected current adjustment range.
Phase-failure protection
Use the phase-loss-sensitive mechanism in the compatible starter.
Trip indication
Wire the NO auxiliary contact to the intended indication circuit.
Contactor interruption
Use the NC contact in the approved control path to stop the motor.

Prepare ABB TA25DU-1.8M 1SAZ211201R2025 for its configured installation using these checks.

Current setting

Match the setting to the motor and duty.

Short-circuit protection

Retain the coordinated upstream protective device.

Reset mode

Assess automatic restart risk before choosing automatic reset.

Contact assignment

Keep 95–96 and 97–98 functions distinct.

Terminal torque

Apply the separate main and auxiliary torque values.

Trip test

Verify the contactor and indication response to a trip.

Technical notes

Signal and interface: The main circuit has a 690 V AC operational rating. Auxiliary contact utilization ratings are separate and depend on voltage and switching category.

Installation boundary: Use the correct terminal torque: 1.4–2.0 N·m for the main circuit and 0.8–1.3 N·m for auxiliary terminals.

Technical basis: ABB Motor Protection and Control Catalogue, 1SBC100179C0201; TA25DU-M technical data 2CDC106056C0201. The 1.30–1.80 A row is TA25DU-1.8M, order code 1SAZ211201R2025. General TA25DU-M ratings apply subject to the stated utilization and mounting conditions.
