Product FAQs
7 answersWhat types of electrical gear is this breaker designed for?
It is engineered for use in Eaton Series G panelboards, Pow-R-Line C panelboards, switchboards, and motor control centers.
Are wire lugs included with the NGC312036EC?
No. This breaker features a stud or tapped pad connection type meant for direct busbar mounting. If you need to terminate standard copper or aluminum cables, a separate lug kit must be sourced.
Will this fit in place of an older ND312036C breaker?
Yes. This NG-frame unit is an exact, drop-in replacement for the discontinued Cutler-Hammer ND312036C.
Can this breaker carry its full nameplate current continuously?
Yes. The NGC312036EC is a 100% rated device. This allows your system to run continuously at the full 1200A capacity without applying the standard 80% derating rule, provided it is installed in an appropriately sized and ventilated enclosure.
What is the specific electronic trip unit equipped on this model?
It comes standard with the Eaton Digitrip 310+ electronic trip unit, which delivers field-adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection parameters.
Can the trip parameters be fine-tuned in the field?
Yes. The onboard electronic trip unit allows for direct field adjustments to the Long-Time, Short-Time, Instantaneous, and Ground-Fault settings to ensure precise coordination with upstream and downstream electrical devices.
What does the Ground-Fault function protect against on this model?
The built-in ground-fault protection detects low-level leakage currents that escape the normal phase conductors. It provides an adjustable trip response to protect equipment from arcing damage and minimize fire risks in commercial or industrial settings.
