Eaton NGC312032E - 1200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

When your electrical system demands dependable, high-current protection, the Eaton NGC312032E delivers robust performance for panelboards and loadcenters. This 1200 A, 600 V, 3-pole bolt-on molded case circuit breaker is engineered to guard circuits against overcurrent and short circuits, keeping critical equipment safe and online.

Key strengths in a single, rugged unit:

• Bolt-on mounting provides a secure, vibration-resistant connection to the bus, reducing loose connections and arcing risks in environments with vibration or heavy loads.
• Thermal-magnetic trip unit delivers stable, repeatable protection — the thermal element handles sustained overcurrent, while the magnetic element responds instantly to short circuits for rapid, clean disconnections.
• Three-pole design supports balanced three-phase distribution, ensuring all phases trip together for coordinated protection of motors, lighting, and feeders.
• OEM compatibility is guaranteed with matching Eaton loadcenters and panelboards, so you get proper fit, UL listing continuity, and straightforward integration with your existing Eaton ecosystem.
• Versatile applications suitable for residential, commercial, and light industrial settings where high-current branch circuits require reliable protection.

Installation and maintenance tips

• Ensure compatibility with your panelboard or loadcenter’s listing. This unit’s 3-pole bolt-on design is intended for Eaton systems designed for this form factor.
• Torque mounting hardware to manufacturer specifications to maintain a solid, conductive bus connection and reduce resistance at the junctions.
• Protect against nuisance trips by confirming the protected load is within the breaker’s rating and the panel’s interrupting capacity.
• Schedule periodic inspections for loose connections or signs of overheating, especially in environments with dust, vibration, or high ambient temperatures.
