      Features:

      • ABB TA25DU-1.8M 1SAZ211201R2025 is a thermal overload relay used to protect motors against sustained overcurrent and phase-loss conditions. It works with a compatible contactor and adjustable current setting, so the motor full-load current, relay range, reset mode and mounting combination must be selected correctly.
      • Adjustable 1.30–1.80 A range with trip class 10A.
      • Manual or automatic reset, phase-loss sensitivity and 1 NO + 1 NC contacts.

      Match the motor current, contactor and fuse coordination before installation.

      TA25DU-1.8M provides thermal overload protection for three-phase motors within its adjustable current range. Correct coordination with the contactor, upstream protection and motor full-load current is required for reliable tripping and reset behavior.
