Eaton ND3800T33W - 800 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton ND3800T33W is a rugged 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short‑circuit protection right in your panelboards and loadcenters. With an 800 A rating at 600 V, this breaker is built to handle substantial, real‑world loads in residential, commercial, and light industrial settings, offering peace of mind where large feeders and critical circuits live. What makes this breaker stand out

• Secure bolt-on mounting—a rigid, vibration‑resistant bus connection that stays tight through equipment activity and environmental vibration, reducing loosening risks and ensuring consistent performance over time.
• Thermal-magnetic trip unit—combines precise thermal overload protection with rapid magnetic response for short-circuit events. This means stable, repeatable protection and faster clearance of high‑fault currents, helping protect conductors and downstream gear.
• Three-pole design for 3-phase systems—ideal for 3‑phase panelboards and loadcenters, providing coordinated protection across all phases and simplifying large‑circuit protection in commercial applications.
• High amperage, broad compatibility—800 A capacity makes it suitable for large branch circuits, reducing the need for multiple devices in demanding applications while staying compatible with matching Eaton OEM load centers and panelboards for reliable, fit‑for‑purpose performance.
• Versatile for multiple environments—engineered for residential, commercial, and light industrial installations where solid protection of feeders, motors, and other high‑demand circuits matters most.
