Technical statements are limited to the documented TA25DU-M configuration. Confirm the installed starter, motor data and complete 1SAZ211201R2025 nameplate before ordering.
ABB is the manufacturer; TA25DU-1.8M is the three-pole thermal overload relay; and order code 1SAZ211201R2025 identifies the 1.30–1.80 A, trip-class-10A version.
Trips the starter control circuit under sustained overload or phase-failure conditions.
The motor nameplate current must lie inside the range and determine the actual dial setting.
Match the ABB AX contactor frame, terminal alignment and starter coordination table.
System relationship: verify the motor current, contactor designation, supply voltage, short-circuit protective device, 95-96/97-98 wiring, reset mode and enclosure conditions before replacement.
Protects three-phase motor circuits against sustained overload and phase-failure conditions.
Adjustable 1.30–1.80 A range; set the dial to the motor nameplate full-load current.
Direct mounting with a compatible ABB AX contactor; verify the frame and terminal alignment.
Verify the complete order code, 1 NC + 1 NO wiring, reset mode, upstream coordination and lifecycle status.
A clear workflow for sourcing, verification, shipment preparation, delivery and product assurance.
Include the complete part number, quantity and delivery destination.
