Product FAQs

6 answers
What trip unit features are included with the ALSI designation on the NGC312038E?

The ALSI designation indicates an electronic trip unit equipped with Long-Time, Short-Time, and Instantaneous adjustments, plus an Arcflash Reduction Maintenance System (ARMS). The ARMS feature allows operators to temporarily lower the instantaneous trip threshold to reduce incident energy during maintenance.

What specific trip unit model is installed in the NGC312038E?

This breaker features a Digitrip 310+ electronic trip unit. It provides precise solid-state protection and includes the ALSI functions required for advanced coordination and arc flash mitigation.

Does the NGC312038E come with standard wire lugs?

No, this breaker features stud or tapped pad terminals. If you are terminating standard copper or aluminum cables, you must purchase and install compatible NG-frame mechanical or compression lugs separately.

What does the "E" at the end of the NGC312038E catalog number indicate?

The "E" suffix indicates that the breaker is equipped with English (Imperial) tapped line and load terminals. This means standard Imperial hardware is required when attaching lugs or bus connections to the breaker.

Which panelboards and switchboards are compatible with the NGC312038E?

This NG-frame breaker is designed for use in Eaton Series G panelboards, switchboards, and motor control centers. It requires the appropriate NG-frame mounting hardware or strap kits specific to your enclosure type.

Can I add internal accessories like a shunt trip to the NGC312038E?

Yes, as part of the Eaton Series G NG-frame family, this breaker accepts standard NG-frame internal accessories. This includes shunt trips, auxiliary switches, alarm switches, and undervoltage releases, which are typically field-installable.
