Eaton | HMCP400L5C | Circuit Breaker | 400A | 3-Pole | 600V | Feed-Through

Eaton HMCP400L5C stands as a robust answer for high-demand electrical distributions. This 400A, 3-pole circuit breaker with a 600V rating and feed-through capability is engineered for maintenance, retrofit, and replacement projects where precise compatibility and dependable protection matter most.

Key capabilities that matter in real-world setups

• Amperage: 400A — ready to handle substantial three‑phase loads without frequent replacements.
• Poles: 3-Pole — designed for three-phase electrical systems common in industrial environments.
• Voltage: 600V — suitable for medium- to high-voltage panelboards and feeders.
• Feed-Through configuration — simplifies wiring to downstream devices and downstream feeders, reducing enclosure clutter and installation time.

Ideal use cases

• Retrofits and replacements in existing Eaton panelboards where a matching 400A, 3P, 600V feed-through breaker is required.
• Maintenance in heavy-load facilities such as manufacturing lines, processing plants, and large motors or drives installations.
• New installations that benefit from a streamlined feed-through approach, enabling easier field servicing and downstream isolation.

Fit, compatibility, and installation considerations

Notes: Confirm fit and ratings before ordering. Part number HMCP400L5C is the best reference for compatibility.

• Compatibility: Designed to align with Eaton panelboards and enclosures that support feed-through breakers.
• Configuration: Ensure a proper three-phase bus arrangement and matching downstream feeder requirements.
• Installation guidance: Follow Eaton’s installation instructions and local electrical codes to ensure safe, compliant operation.

Why choose the Eaton HMCP400L5C

Choosing an OEM Eaton component like the HMCP400L5C delivers consistent performance, reliable trip characteristics, and predictable behavior in demanding industrial environments. With a clearly defined 400A rating, three poles, and a 600V capacity, this breaker is purpose-built for scenarios where large loads must be controlled with precision while keeping downstream connections tidy and accessible through feed-through design. Its part-number specificity helps you verify exact compatibility during maintenance, retrofit, or replacement projects, reducing downtime and risk.

What you get and practical tips for maximum reliability

• One HMCP400L5C circuit breaker designed for 400A, 3‑pole, 600V feed-through applications.
• Practical tip: during installation, plan downstream feeder routes first to leverage the feed-through pathway and minimize wiring congestion in the enclosure.
• Practical tip: periodically inspect lugs and connections for signs of wear, oxidation, or looseness to preserve protective performance over time.
