EC: Eaton Soft Start Controller
Motion control – Drives: The S611 soft starter from Eaton provides OEM and construction customers with an economical and feature-rich product including overload, overcurrent, phase loss, jam and stall protection, and power monitoring capabilities. This is a Control Engineering 2012 Engineers’ Choice honorable mention.
Eaton Corporation expanded its soft start controller solutions for construction and OEM customers to include the S611 soft starter. Gradually accelerating and decelerating the load, the S611 soft starter is an economical solution with robust features that minimize shock to mechanical components, extend system life, increase reliability, reduce maintenance, and lower energy requirements. Featuring an integrated bypass and overload protection, the S611 reduces installation time and costs. Additionally, heating losses are minimized and the S611 design eliminates the need for an external contactor. With a powerful and intuitive user interface, the S611 soft starter provides customers with overload, undervoltage, overcurrent, phase loss, jam and stall protection, and power monitoring capabilities.
Customers can customize parameters to meet specific application requirements. The S611 is easy to use without a manual, simplifying commissioning. An open chassis design makes it easier to service the S611, minimizing downtime and improving service life. With both open and enclosed configurations, the S611 is available in six frame sizes for current ranges from 26 A to 414 A. It can take 230 V to 600 V with power from 40 hp to 350 hp. Additionally, the S611 is rated to National Electrical Manufacturers Association Type 1, 12, 3R, 4, and 4x with high-fault combination ratings up to 100 kA for the most rigorous application requirements. It also meets UL and Canadian Standards Association standards, and is Restriction of Hazardous Substances compliant.
