Product FAQs
6 answersDoes the NGS308032E come with wire lugs included?
No. Eaton NG-frame circuit breakers feature stud or tapped pad terminals standard. Wire lug kits, such as the TA1000NB1, must be purchased separately based on your specific conductor requirements.
What does the 32E suffix indicate on this Eaton breaker?
The 32E designates the Digitrip RMS 310+ electronic trip unit equipped with LSI (Long-Time, Short-Time, and Instantaneous) protection functions. This allows for precise curve shaping and selective coordination.
Can I reverse feed the NGS308032E circuit breaker?
Yes. Eaton Series G NG-frame molded case circuit breakers are suitable for reverse feed applications.
What equipment is compatible with this NG-frame breaker?
This breaker is designed for installation in Eaton Series G panelboards, switchboards, and motor control centers configured for NG-frame footprints.
How does the Digitrip 310+ LSI trip unit improve system protection?
The electronic LSI trip unit allows you to adjust the long delay, short delay, and instantaneous pickup settings. This flexibility enables accurate upstream and downstream breaker coordination to isolate faults without tripping the main breaker.
Is this breaker a direct replacement for older Cutler-Hammer NG-frame models?
Yes. The NGS308032E is an authentic Eaton Series G product and serves as a direct drop-in replacement for legacy Cutler-Hammer breakers with the exact same catalog number.
