NA290-FLAT-TOP | Circuit Breaker | 90A | 2-Pole | 240V

NA290-FLAT-TOP Industrial Circuit Breaker — a robust, purpose-built solution for maintenance, retrofit, and replacement projects where exact specifications matter. This 90A, 2-Pole, 240V breaker is designed to deliver dependable overcurrent protection for demanding industrial circuits.

The flat-top design (NA290-FLAT-TOP) supports streamlined panel layouts and compact mounting in compatible enclosures, helping you maximize space without sacrificing safety or performance. It's especially suited for service panels, motor control centers, or feeders in manufacturing, processing plants, and facility infrastructure.

• Amperage: 90 A — appropriate for mid-to-heavy load circuits
• Poles: 2-Pole configuration for two energised conductors (typical 240V circuits)
• Voltage rating: 240 V nominal
• Compatibility: Use the part number NA290-FLAT-TOP as the primary reference to ensure correct fit; always confirm ratings and panel compatibility before ordering
• Ideal use scenarios: Replacement in existing panels, retrofit projects replacing older flat-top breakers, or new installations requiring a reliable 2-pole 240V solution

How it stands apart: rather than a generic breaker, the NA290-FLAT-TOP is purpose-matched to industrial panels that require precise cross-reference with the flat-top family. By prioritizing the exact part number for compatibility, you reduce the risk of mismatch and installation delays, ensuring a smoother maintenance workflow.

Practical tips for installation and care:

• Before purchase, verify panel labeling and the original part number to ensure a seamless replacement path.
• Store spares in a dry, temperature-controlled area to preserve performance and prevent corrosion of terminals.
• During installation, follow all standard safety protocols and disconnect power before handling; if in doubt, consult a licensed electrician.
