This standard pertains to the requirements for current and voltage protective functions of 1) direct-acting overcurrent electromechanical trip devices, 2) direct-acting overcurrent electronic trip systems, 3) reverse-current trip systems, and 4) undervoltage trip devices that are integral with low-voltage ac (1000 V and below) and general-purpose low-voltage dc (1500 V and below) power circuit breakers covered by IEEE Std C37.13 and IEEE Std C37.14. Additional information, communication, and/or additional internal or external protective functions or devices are not covered by this standard. This standard should not be interpreted to restrict the inclusion of such functionality in the device.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
PC37.17
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 pertains to the requirements for direct-acting current and voltage protective functions of the following that are integral with low-voltage ac and dc power circuit breakers covered by IEEE Std C37.13 and IEEE Std C37.14: a) Direct-acting overcurrent electromechanical trip devices b) Direct-acting overcurrent electronic trip systems c) Reverse-current trip systems for dc circuit breakers d) Undervoltage trip devices This standard describes the requirements for available settings and time delay characteristics for preferred protective functions as well as their 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, and ANSI C37.50.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C37.17-1997
American National Standard for Trip Devices for AC and General Purpose DC Low Voltage Power Circuit Breakers
This standard pertains to the requirements for direct acting current and voltage protective functions of: 1) direct-acting overcurrent electro-mechanical trip devices 2) direct-acting overcurrent electronic trip system 3) reverse-current trip systems 4) undervoltage trip devices that are integral with low voltage AC and DC power circuit breakers covered by ANSI/IEEE C37.13, ANSI/IEEE C37.14, and ANSI C37.16. Additional information, communication and/or additional internal or external protective functions or devices are not covered by this standard. This standard should not be interpreted to restrict the inclusion of such functionality in the device.
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
Requirements for direct acting current and voltage protective functions of direct-acting overcurrent electromechanical trip devices, direct-acting overcurrent electronic trip systems, reverse-current trip systems for dc circuit breakers, and undervoltage trip devices that are integral with low-voltage ac (1000 V and below) and general purpose low-voltage dc (1500 and below) power circuit breakers covered by IEEE Std C37.13(TM), IEEE Std C37.14(TM), and IEEE Std C37.16(TM) are included in this standard. Additional information, communication and/or additional internal or external protective functions or devices are not covered (but also not restricted) by this standard.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
