Allen-Bradley 04-A09ND3 W 193-A1D1 Reversing Contactor

Allen-Bradley 04-A09ND3 W 193-A1D1 Reversing Contactor is a factory‑matched motor-control assembly from Rockwell Automation that pairs a reversing contactor (04-A09ND3) with a 193-A1D1 solid‑state overload relay. The 193‑A1D1 overload relay, a SMP‑1 device, provides motor protection with an adjustable current range of 1.0 to 2.9 A and is designed to mount on compatible Bulletin 100/104 contactors (M05 to A30), enabling integrated overload protection alongside the reversing contactor. This combination is intended for industrial panels where forward/reverse motor operation is required, with the contactor handling main power switching and the overload relay monitoring current to trip if an overload or stall occurs. Used together, they offer a compact means to implement reversible motor control while maintaining protective coordination, suitable for applications such as conveyors, fans, pumps, and other AC motor loads in controlled automation environments. The assembly reflects Allen-Bradley’s approach to modular motor control, allowing technicians to configure a reversing starter with built‑in current protection in a single, recognizable lineup.
