Built for robust power distribution, the Eaton NGS312036E is a Series G molded case circuit breaker tailored for commercial and industrial facilities. It mounts into compatible panelboards and motor control centers, serving as a reliable replacement for legacy ND312036 breakers. While this unit is replaced by the newer PDG53K1200E3NN, it remains essential for existing setups. The Digitrip 310+ unit offers adjustable long-time, short-time, instantaneous, and ground fault (LSIG) protection.
Are wire lugs included with the NGS312036E circuit breaker?
No. Eaton Series G NG-frame breakers come standard with stud and tapped pad terminals. Wire lugs, such as the TA1200NB1 kit, must be purchased separately based on your specific wire size requirements.
Can the NGS312036E replace older Cutler-Hammer ND-frame breakers?
Yes, this Series G breaker is a direct replacement for legacy Cutler-Hammer ND312036 circuit breakers. It fits into the same Eaton panelboards, switchboards, and motor control centers.
What is the modern Power Defense equivalent for the NGS312036E?
The newer Eaton Power Defense replacement for this unit is the PDG53K1200E3NN. However, the NGS312036E remains available for maintaining and expanding existing Series G installations.
What does the 36E in the NGS312036E catalog number indicate?
The 36E designates that the breaker is equipped with a Digitrip 310+ electronic trip unit featuring LSIG protection, which includes adjustable Long-Time, Short-Time, Instantaneous, and Ground Fault functions.
What is required for the ground fault protection to function correctly on a 4-wire system?
When applying this LSIG breaker on a 3-phase, 4-wire system, a separate neutral current sensor must be installed and wired to the trip unit to ensure accurate ground fault detection and prevent nuisance tripping.
What types of enclosures are compatible with the NGS312036E?
This NG-frame breaker is designed for unit-mount or bolt-on installation in Eaton Series G panelboards, switchboards, and motor control centers.
