Product FAQs
8 answersWhat older Eaton or Cutler-Hammer breakers does the NGC312032E replace?
The NGC312032E functions as a direct upgrade and replacement for discontinued ND-frame breakers, such as the ND312032.
What does the 32E in the NGC312032E catalog number signify?
The 32E indicates the breaker is equipped with a Digitrip 310+ electronic trip unit featuring Long-Time, Short-Time, and Instantaneous (LSI) protection functions.
Is the Eaton NGC312032E rated for 100% continuous operation?
No, the NGC312032E is a standard 80% rated circuit breaker.
What types of enclosures and equipment are compatible with the NGC312032E?
This NG-frame breaker is designed for use in Eaton Series G Panelboards, Pow-R-Line C Panelboards, switchboards, and motor control centers.
Does the NGC312032E come with wire lugs installed?
No, this breaker features stud and tapped pad terminals. If you are terminating standard wire, you will need to purchase and install the appropriate NG-frame mechanical or compression lugs separately.
Does this breaker require a separate rating plug?
No, the Digitrip 310+ electronic trip unit on the NGC312032E does not require a separate rating plug. The trip unit has built-in adjustability for its 1200A maximum continuous current rating.
Can I use internal accessories like shunt trips or auxiliary switches with the NGC312032E?
Yes, Series G NG-frame breakers accept common field-fit internal accessories, allowing you to install shunt trips, auxiliary switches, and bell alarms in the field.
Does the NGC312032E include the Arcflash Reduction Maintenance System (ARMS)?
No, the 32E suffix indicates standard LSI functions. Eaton breakers equipped with the Arcflash Reduction Maintenance System typically feature a 39E or similar suffix to indicate ALSI or ALSIG trip functions.
