Starter apparatuses are provided for multiple-winding motors. Such starters can function with a single/combined overload device/circuit, rather than requiring multiple overloads relays and separate overload trip circuits for each motor winding. A microcontroller can keep track of the applicable overload trip points and can control multiple discrete contactors appropriately, via a single/combined overload relay. For a specific implementation, additional and/or alternative desirable functionality can also be afforded, including universal voltage input, true power characteristic sensing for status output/annunciation, integrated damper control, and substantially automated trip point selection and/or implementation.
