Product FAQs

7 answers
What does the "32" in the NGS312032EC catalog number indicate?

The "32" signifies that the breaker is equipped with a Digitrip 310+ electronic trip unit featuring adjustable LSI (Long-Time, Short-Time, and Instantaneous) protection functions.

What does the "C" at the end of the NGS312032EC part number mean?

The "C" indicates that this circuit breaker is 100% rated. This allows the breaker to carry its full 1200A capacity continuously in industrial applications without the standard 80% derating requirement.

Can the Eaton NGS312032EC replace older Cutler-Hammer ND-frame breakers?

Yes, the Series G NG-frame breakers provide a direct replacement for legacy ND312032 breakers, minimizing downtime while fitting into the same Eaton panelboards and switchboards.

Are lugs included with the NGS312032EC circuit breaker?

No, Eaton NG-frame breakers do not ship with lugs. The "E" in the part number indicates it features Imperial tapped line and load terminals, meaning compatible lug kits must be ordered separately based on your specific wire size.

Is the NGS312032EC suitable for reverse feed applications?

Yes, all Eaton Series G NG-frame circuit breakers are designed and approved for reverse feed use.

What does the "S" in the NGS312032EC prefix designate?

The "S" stands for standard interrupting capacity within the NG-frame family. This corresponds to the breaker's rating of 50 kAIC at 480V AC and 85 kAIC at 240V AC.

Is the Eaton NGS312032EC HACR rated?

Yes, all Eaton NG-frame circuit breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
