ARMS setting consideration (EATON devices)

In this version, Eaton’s Arcflash Reduction Maintenance System (ARMS) has been implemented. ARMS uses a separate electronic trip circuit providing faster signal processing and interruption times than the standard ‘instantaneous’ protection. When enabled, the trip unit will trip the breaker with no intentional delay whenever the configured pickup level is exceeded. When enabled, the Maintenance Mode function operates regardless of the instantaneous settings.
