ABB 193-KB75 is a 3‑phase mini bimetallic overload relay in the 193‑K family, designed to protect motors by interrupting current when the load exceeds the programmed trip setting. It offers an adjustable trip range of 5.5–7.5 A and mounts to ABB 100‑K series contactors (such as 100‑K09 or 100‑K12) in a three‑pole protection scheme. The relay supports automatic or manual reset, includes phase‑loss protection, and provides a visible trip indication with IEC Class 10 and UL ratings, delivering reliable protection in compact motor-control panels. Common applications include conveyors, pumps, and machine tools where a compact overload relay is attached directly to the contactor.
