Eaton PDG33M0400E3MJ 400A 3P 600V Circuit Breaker | AmpState

Eaton PDG33M0400E3MJ is a 400 A, 3-pole, 600 V circuit breaker engineered to safeguarding electrical distribution in panelboards, load centers, and larger distribution schemes. Designed for reliability in demanding commercial and industrial environments, it acts as a critical line of defense against overloads and short circuits.

Why this model stands out: it's the go-to choice for retrofit projects where you must preserve existing part numbers to avoid extensive rewiring or re-certification. Keeping the same PDG33M0400E3MJ part number streamlines maintenance planning, stocking, and service scheduling, so downtime is minimized during upgrades or repairs.

• Three-pole protection supports balanced three-phase systems, helping protect all phases with synchronized trip behavior.
• High-current capability at 400 A ensures supply safety for feeders, motor circuits, and distribution panels in mid-to-large electrical installations.
• 600 V rating accommodates common industrial and commercial distribution networks while maintaining safe interrupting capabilities.
• Install-friendly compatibility designed to fit Eaton panelboards and load centers that specify PDG33M0400E3MJ, reducing compatibility risk during replacements.
• Maintenance-friendly sourcing availability from AmpState, with support to confirm fit and compatibility for your specific panel and bus configuration.

Use cases and scenarios: upgrading legacy panels in manufacturing spaces, retrofitting existing distribution with a known, traceable breaker part number, stocking a reliable spare for maintenance planning, or replacing failed units in service entrances where three-phase protection and 600 V isolation are required.
