Eaton NGH312035EC - 1200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton NGH312035EC, a high-current, 3-pole bolt-on molded case circuit breaker built for dependable branch circuit protection in panelboards and loadcenters. With a robust 1200 A rating and a 600 V capacity, this device is engineered to handle demanding electrical environments while delivering consistent protection across every phase.

Why this breaker stands out

• Secure bolt-on mounting for a rigid, vibration‑resistant bus connection, reducing loosening risk in environments with equipment start‑ups or heavy loads.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance—responding to both gradual overcurrents and high‑fault conditions to minimize nuisance trips and protect downstream equipment.
• Three‑pole design ensures simultaneous interruption across all phases, preserving balanced operation in 3‑phase circuits.
• Wide compatibility engineered to work with matching OEM loadcenters and panelboards, ensuring proper fit, electrical coordination, and reliable trips.
• Versatile application suitable for residential, commercial, and light industrial installations where high-current protection is required.

What problems it solves

When large‑current lines, motors, or heavy lighting loads draw more than the circuit can safely handle, the NGH312035EC activates to interrupt the path of fault current. The combination of thermal and magnetic sensing provides a balanced protection scheme: the thermal element handles gradual overloads, while the magnetic mechanism quickly clears short circuits. This dual approach helps prevent wiring insulation damage, reduces fire risk, and minimizes downstream equipment damage in panelboards and loadcenters.

Ideal use scenarios

• Protected feeders in commercial panelboards where high continuous currents are expected
• Residential or light industrial service equipment requiring robust overcurrent and short‑circuit protection
• Retrofits or new installations that demand a bolt‑on MCCB with a proven, OEM-compatible form factor
