All rights reserved. viii Introduction This introduction is not part of IEEE Std C37.17-2012, IEEE Standard for Trip Systems for Low-Voltage (1000 V and below) AC and General Purpose (1500 V and below) DC Power Circuit Breakers. This standard supersedes and upda
29、tes the 1997 edition and all previous revised editions of the original standard published in 1956, all written by the National Electrical Manufacturers Association. In 2003, responsibility for future revisions of C37.17 was transferred from NEMA to IEEE. This standard pertains to direct-acting overc
30、urrent, reverse-current, and undervoltage trip devices of both the electromechanical and electronic types, integral with low-voltage ac and general purpose dc circuit breakers covered by IEEE Std C37.13, IEEE Std C37.14, and IEEE Std C37.16. This revision is aligned with the amended requirements of
31、related assemblies, including low-voltage power circuit breakers (IEEE Std C37.13, IEEE Std C37.14, IEEE Std C37.16, and ANSI C37.50) and metal-enclosed low-voltage power circuit breaker switchgear (IEEE Std C37.20.1TMand ANSI C37.51). Requirements and references for electromechanical devices are in
32、cluded for historical continuity. This standard does not apply to molded-case circuit breakers. This revision of the standard updates the terminology, and reflects technology and current practices in the industry, as well as the capabilities of modern electronic tripping systems. Where appropriate,
33、certain historical information has been retained for reference purposes. It is noted that modern electronic systems may have extended capabilities compared to historic systems.

This standard should not be interpreted to restrict the inclusion of such fu
45、nctionality in the device. 1.2 Purpose The purpose of this standard is to provide the requirements for direct-acting overcurrent and/or undervoltage protective systems associated with low-voltage power circuit breakers. It is aligned with the requirements of related assemblies, including low-voltage
46、 power circuit breaker (IEEE Std C37.13, IEEE Std C37.14, IEEE Std C37.16, and ANSI C37.50) and metal-enclosed low-voltage power circuit breaker switchgear (IEEE Std C37.20.1 and ANSI C37.51). This standard includes minimum requirements for available settings and time delay characteristics as well a
47、s operational and calibration requirements. The functional requirements for the overall circuit breaker, including test requirements (whether design, production, or conformance) are specified in the latest versions of IEEE Std C37.13, IEEE Std C37.14, IEEE Std C37.16, and ANSI C37.50. 2.
