47、tandards Publication was prepared by a technical committee of the NEMA Industrial Control and Systems Section. It was approved in accordance with the bylaws of NEMA and supersedes the indicated NEMA Standards. Replacement:Part 10 supersedes ICS 9 Part 1 Part 11 supersedes ICS 9 Part 2 This standards

48、 publication provides practical information concerning ratings, construction, test, performance, and manufacture of industrial control equipment. These standards are used by the electrical industry to provide guidelines for the manufacture and proper application of reliable products and equipment an

49、d to promote the benefits of repetitive manufacturing and widespread product availability. NEMA standards represent the result of many years of research, investigation, and experience by the members of NEMA, its predecessors, its sections, and committees. They have been developed through continuing consultation among manufacturers, users, and national engineering societies and have resulted in improved serviceability of electrical products with economies to manufacturers and users. One of the primary purposes of this standards publication is to encourage the production
