Eaton | DK2400Y | Circuit Breaker | 400A | 2-Pole | 240V

Eaton DK2400Y is a high-current circuit breaker engineered for 240-volt electrical systems. With a robust 400A rating and a 2-pole configuration, this unit is built to protect and control heavy-duty power distribution in commercial and light industrial panels. Whether you’re performing maintenance, a retrofit, or a replacement, the DK2400Y delivers reliable, consistent protection where it matters most.

Key benefits you’ll appreciate in real-world use:

• High-current protection at 400A to safeguard large feeders and equipment without compromising reliability.
• Two-pole design for balanced, safer shutoffs in 240V circuits.
• Maintainer-friendly choice for retrofit projects and panel upgrades, reducing downtime and compatibility headaches.
• Clear compatibility reference with the DK2400Y part number—useful for matching with existing panels and bus configurations.
• Versatile applications suited to service entrances, distribution panels, and main breaker replacements where 240V systems are standard.

Applications and use cases

This 400A, 2-pole 240V breaker excels in setups where robust overcurrent protection is required for large branch circuits, feeders, or critical equipment. It’s an ideal choice for:

• Maintenance and upgrade projects in commercial buildings with legacy 240V infrastructure.
• Retrofits that require exact part matching to existing Eaton DK-series panels.
• Replacement of worn or obsolete breakers to restore reliable power safety in industrial environments.

Installation and compatibility

Before ordering, verify fit and ratings to ensure seamless integration. The part number DK2400Y is the most reliable reference for compatibility with your panel and bus arrangement. This helps avoid mismatches that could affect performance or safety. If you’re upgrading or replacing, confirm that your panel is designed to accept a 400A, 2-pole, 240V device and that the mounting configuration aligns with Eaton’s DK-series standards.

Why consider the Eaton DK2400Y

• Brand reliability—backed by Eaton’s long-standing reputation for durable power-distribution protection.
• Exact-fit replacement—the DK2400Y is purpose-built for systems that require 400A, 2-pole, 240V protection, helping you maintain consistent electrical performance.
• Clear documentation pathway—using the DK2400Y part number as your compatibility reference simplifies procurement and reduces guesswork.

Practical considerations

Keep in mind that proper installation and sweet-spot compatibility depend on matching the device to your panel’s ratings and physical configuration. If you’re unsure, consult your panel’s documentation or a licensed electrician to confirm that 400A, 2-pole, 240V protection aligns with your system’s protection strategy and safely integrates with existing breakers.
