Engineered for demanding industrial environments, the NGS308036EC is a 100% rated, 800A molded case circuit breaker from Eaton's Series G family. It mounts into compatible Eaton panelboards and motor control centers, replacing the older ND308036 model. The breaker features a microprocessor-based Digitrip 310+ LSIG trip unit, allowing for precise configuration of Long-Time, Short-Time, Instantaneous, and Ground Fault settings. It delivers a 50 kAIC interrupt rating at 480VAC.

Product FAQs
7 answers
What do the "36", "E", and "C" signify in the NGS308036EC catalog number?
In Eaton's Series G nomenclature, "36" indicates a Digitrip 310+ electronic trip unit with LSIG functions (Long-time, Short-time, Instantaneous, and Ground-fault). The "E" specifies imperial tapped pad terminals on the line and load sides, and the "C" designates that the breaker is 100% rated.
Does the NGS308036EC come with wire lugs installed?
No, this breaker features imperial tapped pad (stud) terminals on both the line and load sides. If you are terminating standard wire rather than busbar, you must purchase and install compatible NG-frame wire lugs separately.
What protection functions are included in the LSIG electronic trip unit?
The Digitrip 310+ LSIG trip unit provides adjustable Long-time (overload), Short-time (short circuit), Instantaneous (high-level short circuit), and Ground-fault protection. This allows for precise coordination with other breakers in your electrical system.
What equipment is the NGS308036EC compatible with?
This NG-frame breaker is designed for use in Eaton Series G panelboards, switchboards, and motor control centers (MCCs) that are configured to accept 800A NG-frame unit-mount breakers.
Can the Eaton NGS308036EC be reverse fed?
Yes, Eaton Series G NG-frame circuit breakers are suitable for reverse feed applications.
What does it mean that the NGS308036EC is 100% rated?
A 100% rated circuit breaker can carry its full 800A continuous current rating when installed in an approved enclosure. Standard breakers are limited to carrying 80% (640A) of their maximum rating for continuous loads lasting three hours or more.
Does the ground fault function on this breaker provide personnel protection?
No, the ground fault (G) function on the LSIG trip unit provides equipment ground fault protection. It does not provide the 5mA Class A protection required for personnel safety (GFCI).
