Motor starting and protection moves closer to the process

Motor starter devices and systems provide all the functions necessary for safe starts and stops. They protect against current overload, under voltage, over voltage, short circuit, phase loss, and ground fault. Besides communication capability, some newer trends are solid-state overload relays and hi...

Zusammenfassung:	Motor starter devices and systems provide all the functions necessary for safe starts and stops. They protect against current overload, under voltage, over voltage, short circuit, phase loss, and ground fault. Besides communication capability, some newer trends are solid-state overload relays and highly modular systems of numerous devices. Recent product introductions include 2 major modular systems. Siemens' Sirius 3R line takes the idea of docking from space station structures to refine the art of connecting modular pieces. Rockwell Automation/Allen Bradley's Modular Control System promotes the notion of decentralized motor management. Among trends noted at Cutler-Hammer/Eaton are motor starters based on the microprocessor unit.
