IEEE/ANSI 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.
