Product FAQs
5 answersWhich Eaton enclosures are compatible with the NGH212033E circuit breaker?
This NG-frame breaker is engineered for installation in Eaton Pow-R-Line 4 panelboards, switchboards, and motor control centers.
What type of terminal connections does the NGH212033E use?
It features a feed-thru, bolt-on design with stud/tapped pad terminals. The lugs accommodate four 4/0 AWG to 500 kcmil aluminum or copper wires per phase.
What protection functions are included in the electronic trip unit?
The NGH212033E is equipped with an adjustable Digitrip 310+ LS electronic trip unit, providing Long-Time and Short-Time protection. It does not include instantaneous (I) or ground fault (G) functions.
Is there a newer replacement for the NGH212033E?
Yes, for newer installations, Eaton often supersedes Series G NG-frame breakers with the Power Defense series, such as the PDG52M1200E2NN. However, the NGH212033E remains a direct drop-in replacement for existing Series G setups.
Can this breaker be used for ground fault protection?
No, the 33 in the catalog number indicates it is equipped with an LS (Long-Time, Short-Time) trip unit. It does not include integral ground fault (G) protection. If ground fault protection is required, a different trip unit or external relay system is necessary.
