Struthers-Dunn A175KXX78 Reversing Contactor 115V 60Hz

The Struthers-Dunn A175KXX78 is a robust reversing contactor designed for controlling the direction of AC motors in industrial applications. This model features a compact design with mechanical interlocks to prevent simultaneous forward and reverse operation, ensuring safe motor reversal. It operates on 115V at 60Hz, making it suitable for single-phase or three-phase motor setups in machinery like conveyors, pumps, and hoists. Key benefits include reliable performance in demanding environments, UL listing for safety compliance, and durable construction with phenolic base and silver alloy contacts for extended life. Compared to modern digital controllers, it offers simplicity and cost-effectiveness without needing programming, though it lacks advanced features like overload protection or remote monitoring. Drawbacks may include higher maintenance needs due to mechanical wear over time. Ideal for legacy systems or retrofits, this contactor provides horsepower ratings up to 1 HP at higher voltages, with continuous current handling of 10A. Based on image analysis, the unit appears to be in used condition with visible dust and minor wear, despite being labeled as 'new'—possibly new old stock. No parent/child assets are evident in the images.
