Square D | FIP26090 | Circuit Breaker | 90A | 2-Pole | 600V

Square D FIP26090 Circuit Breaker — a rugged 90A, 2-pole, 600V protection device designed to keep critical electrical systems safe and running smoothly. Whether you’re performing panel maintenance, a retrofit, or a replacement, this breaker delivers reliable, predictable protection when it matters most.

When it comes to compatibility, the FIP26090 is identified by its exact part number, making it the go‑to reference for sourcing replacements and ensuring a seamless installation. Using the correct part number preserves panel labeling, trip characteristics, and coordinated protection that matches the original design.

Key specifications

• Amperage: 90A
• Poles: 2‑Pole
• Voltage: 600V

The two‑pole design interrupts both hot legs simultaneously, providing safer, more reliable protection for circuits feeding equipment and preventing phase‑to‑phase faults. With a 600V rating, this breaker is suitable for higher‑voltage distributions commonly found in commercial and industrial environments, helping you maintain safe power delivery and quick fault isolation.

Ideal use cases

• Panel maintenance where precise spec matching is required
• Retrofits to restore original protection in aging installations
• Replacement in service panels or switchgear that require a 90A, 2‑pole, 600V solution

Practical notes

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, ensuring you get the exact form, fit, and electrical characteristics your system depends on.
