Product FAQs
7 answersWhat does the "G" suffix mean in the LGE340032G catalog number?
The "G" suffix indicates that the breaker is supplied from the factory with standard line and load terminal lugs. If the catalog number ended in "W", it would indicate the breaker is supplied without lugs.
What is the difference between the Eaton LGE340032G and the LGS340032G?
The difference is the interrupting capacity. The LGE340032G is rated for 35kAIC at 480VAC, while the LGS340032G features a higher interrupting rating of 50kAIC at 480VAC. Both share the same 400A LG frame and Digitrip 310+ LSI electronic trip unit.
Does the LGE340032G include ground fault protection?
No, the LGE340032G is equipped with an LSI (Long-Time, Short-Time, Instantaneous) trip unit, which does not provide equipment ground fault protection. If your application requires ground fault protection, you will need a breaker with an LSIG trip unit, such as the LGE340036G.
Is the LGE340032G a 100% rated circuit breaker?
No, the LGE340032G is a standard 80% rated circuit breaker. For continuous loads lasting three hours or more, the load should not exceed 320A (80% of its 400A rating). If your installation requires a 100% rated breaker, you must use the LGE340032GC catalog number.
What does the "32" represent in the LGE340032G part number?
In Eaton Series G nomenclature, the "32" designates a Digitrip 310+ electronic trip unit configured with LSI (Long-Time, Short-Time, and Instantaneous) protection. For comparison, a "33" indicates LS protection, and a "36" indicates LSIG protection.
How is the LGE340032G mounted in an electrical enclosure?
This is a unit-mount, feed-thru circuit breaker. It is designed to be bolted directly to the backpan or mounting chassis of Eaton Series G panelboards, switchboards, or motor control centers, rather than plugging directly onto a busbar system.
What are the advantages of the electronic trip unit in the LGE340032G?
The LGE340032G is equipped with a Digitrip 310+ solid-state electronic trip unit. Unlike traditional thermal-magnetic breakers, this unit allows electricians to precisely adjust the Long-Time, Short-Time, and Instantaneous (LSI) pickup and delay settings. This flexibility is critical for achieving proper selective coordination in commercial and industrial power systems.
