Eaton NGH312036EC - 1200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton NGH312036EC is a high-capacity, 1200 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to protect the heart of your electrical distribution. Engineered for dependable branch circuit overcurrent and short-circuit protection, this unit integrates seamlessly into panelboards and loadcenters, delivering robust performance across residential, commercial, and light industrial applications.

Why this breaker stands out

• Secure bolt-on mounting: A rigid connection to the bus minimizes vibration and movement, promoting a stable, long-lasting electrical path that resists loosening over time.
• Thermal-magnetic trip unit: Combines precise thermal and magnetic protection for consistent, repeatable tripping behavior across a wide temperature range, reducing nuisance trips and enhancing safety.
• 3-pole configuration: Ideal for 3-phase systems, enabling coordinated protection for commercial and light industrial equipment and circuits.
• High current and voltage ratings: 1200 A continuous capacity and a 600 V rating accommodate demanding loads while maintaining reliable protection.
• OEM panelboard compatibility: Designed to match with Eaton’s own loadcenters and other OEM panelboards, ensuring proper fit, bus alignment, and electrical coordination.

Ideal use cases and installation considerations

Perfect for branch circuits where high-current protection is essential—industrial feeders, commercial distribution panels, and large residential installations that require robust, reliable protection. When upgrading or replacing breakers, this unit’s bolt-on mounting provides a sturdier connection in vibration-prone environments or where panelboard chassis flex is a concern. To ensure optimal performance, verify that your panelboard is rated for bolt-on molded case breakers in the NGH series and coordinate with matching OEM components for seamless operation.

What this means in practical terms

• Reliability you can trust: Expect stable protector performance under varying loads and ambient conditions, thanks to the integrated thermal-magnetic protection.
• Simplified serviceability: Bolt-on design facilitates straightforward replacement and servicing without compromising bus integrity.
• Versatile protection: With its high amperage rating and 3-pole configuration, it’s well-suited for complex distribution schemes that demand solid short-circuit protection and rapid isolation of faults.
