Product FAQs
8 answersWhat does the "C" suffix indicate in the NGH308033EC part number?
It signifies that the breaker is 100% rated [1.2.1]. This allows the circuit breaker to carry its full 800-amp continuous current rating indefinitely, rather than being derated to the standard 80% limit.
What does the "E" in the catalog number NGH308033EC specify?
The "E" indicates the breaker is supplied with imperial-tapped line and load connections. It requires standard imperial hardware for terminating busbars or bolt-on lugs, as opposed to metric threads.
Does the NGH308033EC ship with wire lugs?
No, this breaker does not include lugs from the factory. It is equipped with stud/tapped pad terminals. Wire lug kits must be purchased separately based on your specific conductor size and material requirements.
Can this NG-frame breaker be reverse fed?
Yes, all Eaton NG-frame Series G circuit breakers are designed to be suitable for reverse-feed applications.
Does the electronic trip unit require a separate rating plug?
No rating plug is required. The NGH308033EC features a Digitrip 310+ electronic trip unit with fully adjustable long-time and short-time (LS) pickup and delay settings built directly into the device.
What equipment is the NGH308033EC designed to mount in?
This Series G breaker is engineered for installation in Eaton Pow-R-Line 4 panelboards, as well as compatible OEM switchboards and motor control centers.
Does the trip unit provide true RMS sensing?
Yes, the integrated Digitrip electronic trip unit utilizes true RMS sensing. This provides accurate overcurrent protection and helps prevent nuisance tripping in electrical systems with high harmonic distortion.
Are field-installable accessories available for this breaker?
Yes, it accepts standard Eaton Series G internal accessories, including shunt trips, undervoltage releases, auxiliary switches, and bell alarms. These install directly into designated accessory cavities.
