Motor Starters & Contactors

Motor starters, contactors, and related control components used to start, stop, and protect motors in pumps, fans, and other onboard equipment. A contactor switches motor power under control-circuit command; a coordinated starter adds appropriate overload and short-circuit protection. Check motor horsepower or kW at the operating voltage, coil supply, duty and enclosure constraints. For reversing or automation, auxiliary contacts and interlocks are also important. Ward’s catalog carries ABB and Schneider control components for pumps, ventilation and other vessel machinery.
