IEEE PC37.17/D7, January 2022 IEEE Draft Standard for Trip Systems for Low-Voltage (1000 V and below) AC and General Purpose (1500 V and below) DC Power Circuit Breakers
Institute of Electrical and Electronics Engineers (IEEE)
Scope
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 bre...
