21、WITCHES SUITABLE FOR USE IN STRONG MAGNETIC FIELDSE-1 ICS 5-2000 (R2005, R2010) Page iv Foreword This Standards Publication was prepared by a technical committee of the NEMA Industrial Automation Control Products and Systems Section. It was approved in accordance with the bylaws of NEMA and supersed

22、es the indicated NEMA Standards Publication. This Standards Publication supersedes ICS 5-1993 Revision 1, November 1996. This Standards Publication provides practical information concerning ratings, construction, test, performance and manufacture of industrial control equipment. These standards are

23、used by the electrical industry to provide guidelines for the manufacture and proper application of reliable products and equipment and to promote the benefits of repetitive manufacturing and widespread product availability. NEMA Standards represent the result of many years of research, investigatio

24、n 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 manufac

25、turers and users. One of the primary purposes of this Standards Publication is to encourage the production of reliable control equipment which, in itself, functions in accordance with these accepted standards. Some portions of these standards, such as electrical spacings and interrupting ratings, ha

26、ve a direct bearing on safety; almost all of the items in this publication, when applied properly, contribute to safety in one way or another. Properly constructed industrial control equipment is, however, only one factor in minimizing the hazards which may be associated with the use of electricity.

27、 The reduction of hazard involves the joint efforts of the various equipment manufacturers, the system designer, the installer and the user. Information is provided herein to assist users and others in the proper selection of control equipment. The industrial control manufacturer has limited or no c

28、ontrol over the following factors which are vital to a safe installation: a. Environmental conditions b. System design c. Equipment selection and application d. Installation e. Operating practices f. Maintenance This publication is not intended to instruct the user of control equipment with regard t

29、o these factors except insofar as suitable equipment to meet needs can be recognized in this publication and some application guidance is given. This Standards Publication is necessarily confined to defining the construction requirements for industrial control equipment and to providing recommendati

30、ons for proper selection for use under normal or certain specific conditions. Since any piece of industrial control equipment can be installed, operated and maintained in such a manner that hazardous conditions may result, conformance with this publication does not by itself assure a safe installati

31、on. When, however, equipment conforming with these standards is properly selected and is installed in accordance with the National Electrical Code and properly maintained, the hazards to persons and property will be reduced. To continue to serve the best interests of users of Industrial Control and

32、Systems equipment, the Industrial Automation Control Products and Systems Section is actively cooperating with other standardization organizations in the development of simple and more universal metrology practices. In ICS 5-2000 (R2005, R2010) Page v this publication, the U.S. customary units are g

33、radually being supplemented by those of the modernized metric system known as the International Systems of Units (SI). This transition involves no changes in standard dimensions, tolerances, or performance specifications. NEMA Standards Publications are subject to periodic review. They are revised f

34、requently to reflect user input and to meet changing conditions and technical progress. Proposed revisions to this Standards Publication should be submitted to: Vice President, Technical Services National Electrical Manufacturers Association 1300 North 17th Street, Suite 1752 Rosslyn, Virginia 22209

44、ses of this part the following definitions apply. abnormal conditions of use: Situations where an electromagnet, although energized, has failed to close, or where a transformer core is saturated. A control-circuit switch is required to break the current corresponding to such abnormal condition of us

45、e. conditions of use: The principal load-switching application of a control-circuit switch as indicated for the various utilization categories in Table 1-4-3. dry reed switch: A switching device comprised of two or more ferromagnetic reed-like contact-carrying arms which are sealed in a nonmagnetic

46、capsule, usually a glass tube, without the presence of a liquid. The free end(s) are actuated by a change in a magnetic field, making or breaking electrical contact. fanout: A rating given to one pole of a coil-operated switching device which represents the maximum number of coils of identical devic

47、es which can be controlled in parallel by that pole. form “A” contacts: A contact arrangement which has single-pole, single throw, normally open contacts. The function of this arrangement is to close a circuit when actuated. form “B” contacts: A contact arrangement which has single-pole, single thro

48、w, normally closed contacts. The function of this arrangement is to open a circuit when actuated. form “C” contacts: A contact arrangement which has single-pole, double throw contacts with three terminals, one for normally open, one for normally closed and one common. The function of this arrangemen

49、t is to transfer a circuit when actuated. form “Z” contacts: A contact arrangement which has single-pole, double-throw contacts with four terminals, two for normally open and two for normally closed. The function of this arrangement is to open one circuit and close the other. mercury-wetted reed switch: Similar to a dry reed switch except that the contacts are wetted by a film of mercury. normal conditions of use: Use of a control-circuit switch to close, maintain and open circuits which contain an electromagnet, the magnetic circuit of which is open at the time when the
