Product FAQs
8 answersWhat type of trip unit is installed in the NGC308039E?
This breaker features a Digitrip 310+ electronic trip unit with ALSIG functions (Adjustable Long-Time, Short-Time, Instantaneous, and Ground Fault). It also includes an Arcflash Reduction Maintenance System (ARMS) to enhance personnel safety during maintenance.
What panelboards and switchboards are compatible with the NGC308039E?
This NG-frame breaker is designed for use in Eaton Series G Panelboards, Pow-R-Line C Panelboards, Motor Control Centers, and compatible switchboards.
Does the NGC308039E come with lugs installed?
No, Eaton NG-frame circuit breakers typically do not ship with lugs. It features a bolt-on, stud and tapped pad connection, so appropriate line and load lugs must be sourced separately based on your specific wire size requirements.
Can the Eaton NGC308039E be reverse fed?
Yes, all Eaton NG-frame molded case circuit breakers are suitable for reverse feed applications.
What does the "C" in the NGC308039E catalog number signify?
In Eaton Series G nomenclature, the "C" indicates the interrupting capacity tier. For the NG-frame, it specifies a high-interrupting rating of 100 kAIC at 480VAC and 200 kAIC at 240VAC.
What does the "39" in the NGC308039E part number represent?
The "39" designates the specific Digitrip 310+ electronic trip unit installed. This indicates the breaker includes ALSIG (Long-Time, Short-Time, Instantaneous, Ground Fault) protection along with the Arcflash Reduction Maintenance System (ARMS).
Is the NGC308039E rated for 80% or 100% continuous operation?
The standard NGC308039E is 80% rated. If your application requires a 100% continuous current rating, you will need to source the NGC308039EC catalog number instead.
What does the "E" suffix mean on the NGC308039E?
The "E" suffix indicates that the breaker is equipped with Imperial tapped line and load terminals.
