MDL3800WK | Circuit Breaker | 800A | 3-Pole | 600V

The MDL3800WK Industrial Circuit Breaker is engineered for demanding 600V, three-phase environments where uptime and protection matter. With an 800A current rating and a 3-Pole configuration, this unit delivers fast, coordinated interruption across all three phases to safeguard motors, drives, and power distribution panels from overloads and short circuits.

Designed for maintenance, retrofit, and replacement projects where exact specs are non-negotiable, the MDL3800WK offers a precise compatibility reference that simplifies ordering and service planning. Rely on the part number MDL3800WK as your best indication of matching characteristics, ensuring you don’t gamble with fit or performance in critical applications.

Key features that matter in the real world

• 800A amperage rating— capable protection for high-load equipment without unnecessary trips.
• 3-Pole configuration— ensures balanced protection across all three phases, which helps prevent phase imbalance and motor damage.
• 600V operation— suitable for standard industrial three-phase distribution networks common in manufacturing, processing, and heavy machinery environments.
• Clear compatibility reference— use the MDL3800WK part number to verify fit and ratings against your existing equipment and control panels.

Practical use cases

• Panel retrofits where your system requires a higher-capacity, three-pole 600V breaker to accommodate upgrades in motors or drives.
• Maintenance spares for facilities with frequent commissioning or repairs on 600V, three-phase equipment.
• Replacement parts for legacy installations that specify an 800A, 3-Pole, 600V protection device without changing the surrounding electrical architecture.

Fit and compatibility guidance

To ensure the MDL3800WK is the right choice, verify three core specifications before ordering:

• Amperage: 800A
• Poles: 3-Pole
• Voltage: 600V

Use the part number MDL3800WK as the primary compatibility reference. Confirm that your panel, bus arrangement, and any trip-unit or accessory requirements align with this model. If your system mandates a different configuration (e.g., more poles or a different voltage), consider alternative models designed for those exact specs.
