Introduction This introduction is not part of IEEE Std C37.16-2009, IEEE Standard for Preferred Ratings, Related Requirements, and Application Recommendations for Low-Voltage AC (635 V and below) and DC (3200 V and below) Power Circuit Breakers. IEEE Std C37.16 was f
5、ormerly the responsibility of a NEMA working group; this responsibility was transferred to IEEE Standards Association in January 2003. The Low Voltage Switchgear Devices subcommittee of the Switchgear Committee of the IEEE Power and Energy Society is now responsible for maintenance and revision of I
6、EEE Std C37.16. The IEEE Preferred Ratings, Related Requirements, and Application Information for Low-Voltage Power Circuit Breakers working group made the following changes to keep it up to date with the evolution of low voltage circuit breakers. Changes made in this version include: Tables 1 and T
7、able 2 were replaced by individual paragraphs with each rating. A new Table 1 and Table 2 link frame size to interrupting rating. References to IEEE Std C37.29, which has been withdrawn, were deleted. The tables on motor application were deleted. The user is encouraged to consult relevant standards,
8、 including NEMA MG-1 and NFPA 70. The tables on anode circuit breakers and low-voltage ac circuit protectors were deleted due to lack of product for many years. Rows were deleted from the dc transit breaker tables related to the 53 msec time constant due to lack of product. Tables have been rearrang
9、ed by application and numbered sequentially. Annex A lists the table number from the previous edition and the location of that information in this edition Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with the provisions
10、of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements.
