IEEE C37.17/D9, March 2010 IEEE Draft Standard for Trip Systems for Low-Voltage (up to 635 V) AC and General Purpose Low-Voltage (up to 600 V) 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 4) undervoltage trip devices, that are integral with low-voltage ac (635V and below) and general purpose low-voltage dc (600V and below) power circuit breakers cov...
