Eaton | LDC3400W | Circuit Breaker | 400A | 3-Pole | 600V

The Eaton LDC3400W circuit breaker is a rugged 400A, 3-pole device tailored for 3‑phase, 600V systems. Designed with maintenance, retrofit, and replacement projects in mind, it delivers dependable protection where exact specifications matter and downtime is costly.

Key specifications:

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 600V

Why this breaker stands out

• Exact fit for compatibility: The part number LDC3400W serves as the best reference to match this breaker with your Eaton panel or switchgear. Always confirm fit and ratings before ordering to ensure seamless replacement.
• Reliable protection for 3-phase systems: With a 3-pole configuration, all three conductors are isolated simultaneously, helping ensure safe, coordinated shutdown across a 600V network during faults.
• Ideal for maintenance, retrofit, and replacement: This unit is purpose-built for upgrading aging infrastructure or expanding capacity in Eaton-compatible panels, making swaps quicker and more predictable.

Ideal use cases

• Upgrading or refurbishing industrial panels that run on 3‑phase 600V power with 400A feeders, such as manufacturing lines or large equipment arrays.
• Retrofitting warehouses, data centers, or commercial facilities that require a robust, easily replaceable 400A, 3‑pole protective device.
• Replacing existing breakers in service entrances or motor control centers where a 400A rating and 600V maximum are required.

Practical tips for installation and reliability

• Verify panel listing and enclosure compatibility using the LDC3400W part number as the primary reference.
• Check panel labeling to confirm the breaker’s amperage, pole count, and voltage rating before installation.
• Plan a controlled power-down to minimize downtime during retrofits or replacements, and have appropriate safety procedures in place.

Note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.
