Eaton KDC3400F Circuit Breaker

The Eaton KDC3400F is a 3-pole, 600V frame-only circuit breaker rated for 400 A, designed for electrical distribution systems that require a frame-based protection device. Because it is a frame-only model, it provides the structural frame, mounting hardware, and connection interfaces needed to accept a compatible trip unit, enabling full overcurrent protection for a 3‑phase circuit when paired with the proper Eaton module. As part of Eaton's KDC family, the KDC3400F is specified for operation up to 600 V and 400 A, offering a high-current solution for demanding industrial environments where reliable phase protection is essential. This configuration is suitable for applications requiring a separable trip unit approach, giving installers the flexibility to select protection characteristics that match system coordination and safety requirements.
