Eaton PDG33M0400E3RN Circuit Breaker, 400A, 3-Pole, 600V

The Eaton PDG33M0400E3RN circuit breaker is engineered for demanding industrial service, maintenance, and replacement projects. With a 400-amp rating across a 3-pole configuration and a 600-volt maximum, this breaker delivers dependable protection for large three-phase electrical systems and heavy motor loads.

• Current rating: 400 A — ideal for serving substantial equipment and distribution panels without frequent tripping.
• Pole configuration: 3-pole — ensures simultaneous disconnection of all three phases for safer shutdown of three-phase circuits.
• Voltage rating: up to 600 V — suitable for most industrial power distribution environments and motor applications.
• Part number for compatibility: PDG33M0400E3RN — use this exact part number to verify fit with your application and panel requirements.

Why this matters in real-world settings: industrial facilities often run high-current, three‑phase motors and feeders where a single-pole solution could leave remaining phases energized. The PDG33M0400E3RN provides coordinated protection, helping prevent damage from overloads or short circuits and supporting safer maintenance workflows.

Ideal use cases include main protection or replacement in large industrial panels, motor control centers, and service disconnects where a reliable 3‑phase breaker is essential. It’s the practical choice for upgrades, refurbishments, and ongoing maintenance projects in manufacturing, processing plants, and heavy equipment environments.

If you’re uncertain about compatibility, this part number is your first verification step. Verify fit by part number and application requirements to ensure seamless installation.
