Allen-Bradley 193-EA1CB Industrial Control Relay

Allen-Bradley 193-EA1CB is a solid-state overload relay (Bulletin 193) that provides motor protection by monitoring current and opening the circuit when overload conditions are detected. Designed for direct mounting to compatible Allen-Bradley IEC contactors, it works with NEMA Size 00, 100-M05, and 100-C25 contactors to form a compact motor-protection module. The unit features a 0.32–1.0 A adjustable trip range and a rated operational voltage up to 690 V AC, making it suitable for a wide range of industrial motors. It offers Class 10 protection with a manual reset, and it includes a front-reset mechanism and a visual trip indicator to clearly signal fault status. An auxiliary contact set provides 1 NO and 1 NC outputs for status signaling or interlock logic. Built with an industrial molded thermoplastic housing, the 193-EA1CB is part of Allen-Bradley’s Bulletin 193 family, specifically the SMP-1 solid-state overload relay lineage. This relay is intended to be used as part of a protective assembly on standard Allen-Bradley contactors and is commonly integrated into industrial control panels to guard motors against overheating and electrical faults.
