Why this breaker matters for your panel

In three-phase systems, a 3-pole breaker interrupts all hot conductors simultaneously, providing balanced protection across the circuit and preventing uneven loading that can compromise equipment and safety. The FI36080CBA is suited for use in panels and enclosures that accept Square D devices with this exact configuration, ensuring a clean, reliable upgrade or replacement path.

Ideal use cases

Ideal for service panels, feeders, and distribution circuits that require:

• Upgrading or repairing three-phase 600V circuits
• Retrofitting older installations to current protection standards
• Maintaining panel reliability during routine maintenance or component swaps

Practical tips for compatibility and installation:

• Always verify the panel model and the FI36080CBA's fitment against your equipment’s documentation before ordering.
• Use the FI36080CBA as the primary reference when confirming compatibility, bus style, and mounting orientation.
• Keep the exact part number on hand during service calls to avoid mismatches in trip characteristics or mounting kits.
