Description
Built for high-capacity industrial applications, this 800A NG-Frame breaker utilizes an advanced Digitrip 310+ electronic trip unit. It offers adjustable long-time, short-time, and ground fault (LSG) sensing to optimize coordination. This bolt-on unit mounts into Eaton Series G panelboards and motor control centers. It serves as a reliable component for existing infrastructure, though Eaton has introduced the PDG53M0800E5NN as its modern substitute.Specifications

Product FAQs
7 answersWhat equipment is compatible with the NGH308035E circuit breaker?
This NG-frame breaker is designed for installation in Eaton Series G panelboards, switchboards, and motor control centers.
What protection functions are included in the NGH308035E trip unit?
The Digitrip 310+ electronic trip unit provides Long-Time, Short-Time, and Ground-Fault (LSG) protection. This allows for precise curve shaping and selective coordination in complex electrical systems.
Is the NGH308035E rated for 100 percent continuous current?
No, this standard NGH-frame breaker is 80 percent rated.
Does the NGH308035E require a separate rating plug?
No, the integrated Digitrip 310+ electronic trip unit features selectable long-time delay and pickup settings directly on the breaker, eliminating the need for an external rating plug.
What type of terminal connections does the NGH308035E use?
The E suffix in the catalog number indicates it comes standard with imperial tapped line and load terminals for bolt-on connections. If copper or aluminum wire lugs are needed, they must be ordered separately.
What is the difference between the NGH308035E and the NGS308035E?
The difference is the interrupting capacity. The NGH frame features a high interrupting rating of 65kA at 480VAC, while the standard NGS frame is rated for 50kA at 480VAC.
How is ground fault protection configured on the NGH308035E?
The integrated Digitrip 310+ LSG trip unit features adjustable ground fault pickup and flat response delay settings. When applied in a 3-phase, 4-wire system, an external neutral current sensor is required for accurate ground fault monitoring.
