Product FAQs
7 answersWhat types of enclosures or equipment are compatible with the NGH308036E breaker?
The NGH308036E is designed for use in Eaton Pow-R-Line 4 panelboards, switchboards, and motor control centers.
What does the "36E" signify in the NGH308036E catalog number?
The "36" indicates it is equipped with a Digitrip 310+ electronic trip unit featuring LSIG (Long-Time, Short-Time, Instantaneous, and Ground Fault) protection. The "E" designates that the breaker includes Imperial tapped line and load conductor terminals.
Does the NGH308036E come with standard wire lugs?
No, this breaker comes standard with Imperial tapped stud/pad terminals for bolt-on connections. If you are terminating standard copper or aluminum wire, you must purchase and install compatible mechanical or compression lugs separately.
How is the ground fault protection configured on the NGH308036E?
The Digitrip 310+ LSIG trip unit includes adjustable ground fault pickup and delay settings. If installed in a 4-wire system, a separate neutral current sensor must be installed and wired to the trip unit to ensure accurate ground fault sensing.
Can the NG-frame NGH308036E replace an older ND-frame breaker?
The Series G NG-frame was introduced as an upgrade to the older Series C ND-frame. While they share similar applications, their physical dimensions and mounting footprints differ, so direct replacement may require panel modifications or retrofit kits.
Are the trip settings on the NGH308036E adjustable?
Yes, the Digitrip 310+ electronic trip unit allows you to adjust the Long-Time pickup and delay, Short-Time pickup and delay, Instantaneous pickup, and Ground Fault pickup and delay to coordinate with your specific system requirements.
Is the NGH308036E suitable for reverse feed applications?
Yes, Eaton NG-frame circuit breakers are suitable for reverse feed use, allowing power to be supplied to either the line or load terminals without compromising the breaker's protective functions.
