Benefits of the R-Frame 310+ breaker:

• No DIP switches or rating plugs needed. The 310+ has adjustable trip settings integral to the electronic trip unit
• Remote Arcflash Reduction Maintenance System is an available feature. This feature increases worker safety by providing an accelerated instantaneous trip to reduce arc flash potential
• Ground fault alarm, no trip, is an option. In addition to offering ground fault and high load alarms, the 310+ allows for ground fault alarm, no trip. This is essential for critical applications that must stay online when a ground fault is present
• ZSI is an available feature. This feature enables the breaker to communicate with the immediate upstream or downstream ZSI-enabled breakers to clear faults in the shortest amount of time using the breaker closest to the fault o • All R-Frame circuit breakers are suitable for reverse-feed use

A full range of world-class accessories:

• Uses the same internal accessories as the standard R-Frame, from auxiliary switches to undervoltage relays
• Choose from a range of external accessories, including handle lock-offs, flex shafts, plug-in adapters and drawout cassettes
• In addition to integrated cause of trip, the RG 310+ built-in test port allows compatibility with Eaton's ammeter/cause of trip display, panelmount ammeter/cause of trip display, and cause of trip LED module
