Product FAQs
7 answersWhat enclosures and equipment are compatible with the NGC312036E?
This NG-frame breaker is designed for installation in Eaton Series G panelboards, switchboards, motor control centers, and standalone enclosures.
How are the wire connections made on the NGC312036E?
This breaker features imperial tapped line and load conductors (stud/tapped pad) for bolt-on unit mounting. Cable lugs are not factory-installed and must be selected separately based on your specific wire size and material.
What does the E suffix in the NGC312036E catalog number indicate?
The E suffix indicates that the breaker is equipped with imperial tapped line and load conductors. This means the terminal pads use standard imperial threading for mounting cable lugs or connecting directly to busbars.
What protection features does the Digitrip 310+ LSIG trip unit offer?
The LSIG designation means the trip unit provides adjustable Long-Time, Short-Time, Instantaneous, and Ground Fault protection. This allows precise coordination with other breakers in your electrical system to isolate faults.
Does the NGC312036E meet NEC requirements for ground fault protection?
Yes. Because it includes integrated Ground Fault protection, it can be used to satisfy National Electrical Code (NEC) requirements for equipment ground fault protection on solidly grounded 480V services of 1000 amps or more.
Can the Digitrip 310+ trip unit be field-tested?
Yes, the trip unit includes a dedicated test port. By connecting a compatible Eaton functional test kit, technicians can verify the performance of the long delay, short delay, and ground fault functions during routine maintenance.
Are the trip units on NG-frame breakers field-replaceable?
No, the Digitrip 310+ electronic trip unit is factory-installed in the NGC312036E and is not designed to be swapped or upgraded in the field.
