Product FAQs
10 answersCan the NGS312033E replace older Cutler-Hammer models?
Yes, the Series G NGS312033E serves as a direct replacement for the legacy Series C ND312033 molded case circuit breaker. It upgrades the older design to the modern Digitrip 310 or 310+ RMS electronic platform.
Is the NGS312033E rated for 100 percent continuous current applications?
No, this breaker is an 80 percent rated device. In accordance with standard electrical codes, the continuous load applied to the breaker should not exceed 960 amps, which is 80 percent of its 1200A nominal rating.
Are mounting lugs included with this NG-frame breaker?
No, this unit comes standard with imperial tapped pads on the line and load sides. Mechanical or compression terminal lugs must be specified and purchased separately based on your conductor type and size requirements.
Which internal accessories can be installed in this circuit breaker?
The NGS312033E accepts standard Eaton Series G internal accessories. Panel builders can add shunt trips, auxiliary switches, alarm switches, and undervoltage releases to meet specific control panel requirements.
What protection adjustments are available on the LS trip unit?
The electronic Digitrip 310+ LS trip unit allows for precise adjustments of Long-Time (overload) and Short-Time (short circuit) parameters. This adjustability helps electricians safely coordinate the breaker's response time with other downstream electrical devices.
Does the NGS312033E feature integrated ground fault protection?
No, this specific model features an LS trip unit, meaning it provides Long-Time and Short-Time protection only. If ground fault protection is required for your installation, you must source a breaker variant equipped with an LSG trip unit.
Can this breaker be wired for reverse feed configurations?
Yes, the NGS312033E is reverse feed capable. This means electrical power can be safely supplied to either the line or load side terminals without affecting the breaker's performance, safety ratings, or tripping accuracy.
What types of distribution equipment is this breaker designed for?
This unit mount breaker is engineered for integration into Eaton Series G panelboards, switchboards, and motor control centers. It is typically secured using a standard bolt-on connection method.
What wire sizes are supported when adding standard terminal lugs to this breaker?
When equipped with the appropriate Eaton terminal lug kits, the connections on this breaker can accommodate copper or aluminum conductors ranging from 4 AWG up to 500 kcmil.
Is this circuit breaker suitable for HVAC equipment?
Yes, the NGS312033E carries an HACR rating. This certification ensures the breaker is rigorously tested and approved for safe use with heavy-duty heating, air conditioning, and refrigeration equipment in industrial facilities.
