Allen-Bradley 193-T1DC90P Overload Relay for Motor Protection

The Allen-Bradley 193-T1DC90P (193-T1DC90P) is an overload relay designed for industrial motor control and motor protection applications. Operating as part of the Allen-Bradley Bulletin 193 family, this unit is engineered to protect electrical motors, contactors, and motor starter circuits from sustained overcurrent and thermal overload conditions. It monitors phase currents during continuous machine operation, tripping to interrupt control power to the contactor coil when an excessive thermal or current threshold is detected, thereby preventing motor insulation breakdown and catastrophic equipment failure. The device features an integrated housing with terminal connection points designed for secure panel mounting or direct integration with compatible contactor assemblies. With an approximate net weight of 10 kg, the 193-T1DC90P provides robust operational stability across industrial motor setups, manufacturing assembly lines, pumps, fans, compressors, and material handling systems. By delivering dependable overload sensing, this relay helps maintain machine reliability and prevent downtime in heavy-duty motor branch circuits.
