Furnas WR44R Series A Reversing Drum Switch

The Furnas WR44R Series A is a robust, manual reversing drum switch designed for controlling the direction of electric motors in industrial applications. Manufactured by Furnas Electric Company (now part of Siemens), this switch features a cylindrical, watertight enclosure suitable for harsh environments, with a lever-operated mechanism offering Forward, Off, and Reverse positions. It is ideal for use in machinery such as conveyors, hoists, winches, and small machine tools where motor reversal is required. Key benefits include its durable cast iron or aluminum construction, UL-listed safety, and reliable performance in wet or dusty conditions, providing an advantage over standard open switches by ensuring watertight conductor connections to prevent electrical hazards. Drawbacks may include its manual operation, which lacks automation compared to modern electronic controllers, and potential wear on mechanical contacts over time. This model supports single-phase and three-phase motors up to 2 HP, with high voltage ratings for versatility. Compared to similar products like those from Square D or Cutler-Hammer, the WR44R offers superior environmental resistance at a lower cost for legacy systems. Based on attached images, the unit appears used with signs of rust and wear, but functional; no serial number visible, and no attached child assets. For resources, refer to Siemens/Furnas legacy manuals (e.g., Class 58 Drum Controller Guide: https://www.siemens.com/download?A6V10103758) and general datasheets (search 'Furnas WR44 datasheet PDF' for HP rating tables). Estimated market price for used condition: $75-150 USD, based on eBay and industrial surplus listings.
