Motor Starters, Contactors & Motor Controls

Electrical Supplies Unlimited (ESU) has more than 40 years of experience in the electrical supply business, providing electrical equipment to contractors, electricians, businesses, and industrial customers. We buy, sell, and maintain a large inventory of motor starters, contactors, and motor controls, including new, used, surplus, obsolete, and hard-to-find equipment. Our experience and extensive inventory allow us to help customers locate both current products and older equipment that may be difficult to source.

Large Selection of Motor Starters & Contactors

ESU stocks a wide selection of motor starters, magnetic starters, contactors, overload relays, and related motor control equipment. These products are used in industrial machinery, HVAC systems, manufacturing equipment, pumps, motors, and electrical control systems. We specialize in sourcing specific replacement components, including discontinued and obsolete products, when an exact match is needed for existing equipment.

Major Motor Control Manufacturers

ESU handles motor control equipment from many leading electrical manufacturers, including Allen-Bradley, Square D, Siemens, Eaton/Cutler-Hammer, and General Electric (GE). We also handle equipment from other manufacturers and can help identify products based on the manufacturer, part number, electrical ratings, and other nameplate information. Our inventory can be particularly valuable when customers need replacement equipment for older machinery or electrical systems.

Buy, Sell & Source Motor Controls

ESU not only sells motor starters, contactors, and motor controls—we also buy new, used, surplus, and obsolete electrical equipment. If you have excess motor controls, unused inventory, discontinued equipment, or surplus components from a completed project, contact ESU to see if we are interested in purchasing them. With more than four decades of experience and a large customer base, ESU can help customers source hard-to-find motor control equipment while helping businesses turn surplus electrical inventory into value.
