Eaton Corp. is expanding its soft start controller solutions for construction and OEM customers to provide advanced system information that helps expedite commissioning and minimize downtime. Gradually accelerating and decelerating the load, the S611 soft starter is designed to 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 helps reduce installation time and cost while minimizing heating losses; the design also eliminates the need for an external contactor.
The soft starter is designed to provide overload, undervoltage, overcurrent, phase loss, jam and stall protection, as well as power monitoring; customers can customize parameters to meet specific application requirements. An open chassis design helps simplify service, while the modular design approach helps minimize downtime and improve service life. With both open and enclosed configurations, the S611 is available in six frame sizes for current ranges from 26 to 414 amperes; it can take 230V to 600V from 40 to 350 hp.
