When your facility demands reliable, high-capacity power generation, settling for anything less than proven industrial excellence isn't an option. This Marathon 400KW Generator End delivers the robust performance and UL-certified quality that critical power applications require – and with two units currently available, you have the flexibility to power multiple installations or secure backup inventory for your operation.
Marathon has earned its reputation as a trusted name in commercial and industrial power generation, and this 400KW generator end exemplifies why. Engineered for standby power applications where reliability is non-negotiable, this unit provides substantial power capacity to keep your facility operational during grid failures, planned maintenance, or emergency situations.
UL Listed for Peace of Mind: The UL certification isn't just a formality – it's your assurance that this generator end has undergone rigorous testing and meets stringent safety standards. This certification streamlines your permitting process and provides the documentation required by insurance companies and building inspectors.
New Condition, Factory Quality: These are brand-new units, not refurbished or remanufactured. You receive full factory specifications, pristine components, and the reliability that comes with equipment that hasn't experienced operational wear.
Multiple Units Available: With two generator ends in stock, you have options. Power multiple locations, maintain critical spare capacity, or secure a backup unit for minimal downtime during maintenance cycles. This availability won't last – units of this caliber typically move quickly.
Industry-Standard Integration: The SAE No. 1 flywheel adapter provides compatibility with a wide range of diesel and natural gas engines, giving you flexibility in your complete generator system design. This standardized interface reduces installation complexity and costs.
The 480V three-phase output of this generator end aligns perfectly with commercial and industrial electrical infrastructure. This voltage level minimizes current draw for the same power output, reducing conductor sizing requirements and improving overall system efficiency. Three-phase power also provides smoother, more consistent power delivery – crucial for sensitive electronic equipment and motor-driven machinery.
Power generation equipment represents a critical investment in your facility's operational resilience. This Marathon 400KW generator end offers the capacity to handle substantial electrical loads while maintaining the efficiency and reliability required for standby power systems. Whether you're building a new emergency power system or upgrading existing infrastructure, this generator end provides a foundation of proven performance.
Limited Availability – Two Units in Stock: Generator ends of this capacity and quality don't remain available indefinitely. If your facility requires robust standby power capability, or if you're a contractor serving clients who depend on uninterrupted electrical service, this is your opportunity to secure premium Marathon quality.
