Why this breaker matters for your system

• Two-pole design ensures simultaneous disconnection of both hot conductors in 240 V and higher networks, improving fault isolation and safety in industrial panels.
• The 600 V rating supports modern distribution setups common in manufacturing environments, large electrical rooms, and critical HVAC or motor circuits, providing reliable protection where it’s needed most.
• 400 A capacity is well-suited for protecting large feeders and substantial loads while maintaining stable operation during normal startup transients.

Ideal use cases

• Feeder protection for industrial control panels, machine rooms, and heavy equipment such as large motors and transformers.
• Main or sub-feed protection in commercial facilities with elevated current requirements.
• Replacement or retrofit in existing Eaton installations to maintain consistent protection and compatibility.

What this means for reliability and safety

• Clear, reliable interruption during overcurrent events helps prevent insulation damage, overheating, and fire risk in high-energy installations.
• Predictable trip behavior supports straightforward maintenance planning and faster fault diagnosis.

Installation and compatibility notes

• Ensure the panel or enclosure is rated for 600 V and accepts two-pole, high-current breakers compatible with Eaton KD-series designs.
• Follow local electrical codes and Eaton installation guidelines, including correct torque on terminations to ensure secure, long-lasting connections.
• Consider keeping a spare KD2400KW01 on hand for rapid replacements during maintenance windows to minimize downtime.
