Designed for maintenance, retrofit, and replacement

Use this circuit breaker when upgrading or restoring three-phase panels that require the exact specifications of the NA3P90-FLAT-TOP. It’s purpose-built for scenarios where matching amperage, pole count, and voltage is critical to maintain system protection, trip characteristics, and compatibility with existing panel buses and accessories.

What makes the Flat-Top design unique

The Flat-TOP profile supports clean, aligned mounting within compatible enclosures, helping to minimize gaps and ensure consistent engagement with bus bars during installation. This design detail can simplify retrofit work, improve physical fit inside tight panels, and support reliable operation over the life of the system.

Use cases and ideal applications

• Upgrading three-phase feeders in manufacturing lines and processing equipment
• Retrofits where panels previously used a 90A, 3-pole, 240V protection scheme
• Replacement of aging breakers to restore original protection parameters without changing wire sizing or downstream circuits

Installation and compatibility tips

• Always confirm fit and ratings before ordering—part number accuracy is the best reference for compatibility.
• Use in panels and enclosures that support NA3P-series breakers and a 240V three-phase distribution scheme.
• Follow standard lockout/tagout procedures and manufacturer installation guidelines to ensure safe, proper operation.

If your project requires precise replication of an existing protection scheme, the NA3P90-FLAT-TOP delivers dependable performance with a straightforward path to retrofit or replacement. Engage this breaker to safeguard motors, feeders, and critical 3-phase circuits while maintaining alignment, reliability, and ease of maintenance in your electrical system.
