Compatibility and installation notes

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your panel or distribution equipment. Always ensure the surrounding panel labeling, bus configuration, and terminal dimensions align with the FDC3090L specifications before installation. For best results, reference your system’s catalog or electrical schematic to verify three-phase 600V suitability and three-pole coordination.

Practical guidance for best results

• Handle with power off and follow lockout/tagout procedures during replacement
• Match the FDC3090L to your panel’s model and catalog to avoid compatibility issues
• Store spare breakers in a clean, dry location to prevent corrosion or damage
