      Protect expensive motors from costly overload damage with your choice of magnetic motor starters from Grainger. Most commonly used to safeguard larger 3-phase motors in industrial applications, heavy-duty motor starters include a contactor that completes the circuit to the motor and an electromagnetic overload relay that monitors the current the motor is drawing. One key advantage of a magnetic starter is that its electromagnetic relay is significantly more sensitive than a conventional thermal overload relay, so it can protect motors more effectively. Come to Grainger to find electric motor starters in a wide range of amp and voltage levels.
