Eaton NGH312035E - 1200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton NGH312035E is a rugged 1200A, 600V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. With a purpose-built bolt-on mounting and a thermal-magnetic trip unit, this breaker delivers precise protection for demanding 3-phase electrical systems found in commercial and light industrial environments, while remaining suitable for residential applications where high-current protection is required.

Why this breaker stands out

• Rigid bolt-on mounting provides a secure, vibration-resistant bus connection that stays seated under heavy loads and machinery startup, reducing the risk of loose connections and intermittent faults.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a range of operating temperatures and fault conditions, ensuring fast response to short-circuits while handling overloads predictably.
• OEM-compatible design is engineered to fit alongside matching Eaton OEM load centers and panelboards, simplifying replacement and upgrades without custom modifications.
• High-current, three-phase protection ideal for demanding branch circuits in commercial and light industrial settings, as well as larger residential installations needing robust circuit protection.

Key applications and use cases

• Protect 3‑phase feeder and branch circuits in panelboards and load centers that require a 1200A, 600V rating with reliable short-circuit interruption.
• Replace or upgrade aging breakers in commercial electrical systems where vibration from equipment or heavy loads can loosen connections.
• Install in new construction or retrofit projects that demand a bolt-on solution with proven protection performance and OEM compatibility.
• Ideal for motor control circuits, HVAC equipment, pumps, and other high‑inrush or high‑fault‑current applications common in light industrial environments.
