Allen-Bradley 193-T1AC25 Thermal Overload Relay

Allen-Bradley 193-T1AC25 is a bimetallic thermal overload relay in the 193-T1 MCS family, designed to protect IEC-compatible motors within starter assemblies. It provides motor overload protection with a setting range of 21.0–25.0 A, enabling tuning to the motor’s full-load current. This model is intended for use with Allen-Bradley 100-C contactors (for example, 100-C23), delivering coordinated protection in a standard motor starter. As a thermal overload relay, it trips to disconnect the motor when current exceeds the selected range, helping prevent overheating and damage to drive systems. The 193-T1AC25 designation identifies the 25-A end of the 21–25 A range and is documented in Rockwell Automation literature alongside other 193-T1 variants.
