NAL36800 - 800 Amp Circuit Breaker

NAL36800 - 800 Amp Circuit Breaker

Safeguard your facility's power distribution with the NAL36800 800 A circuit breaker—a high-capacity, three-pole protective device built for demanding commercial and industrial settings. With thermal-magnetic trip technology, this unit offers dependable protection against overloads and short circuits while delivering long service life in heavy use. Its feed-through design, complete with mounting lugs on both the line and load ends, simplifies retrofits or new installations.

Key Features and Benefits

• Thermal-Magnetic Trip: Combines thermal (overload) and magnetic (short circuit) protection in one device for better safety and flexibility.
• High Interrupting Rating: Capable of interrupting up to 100,000 AIC at 240 VAC, securing your system even under fault stress.
• Molded-Case Construction: Durable casing that resists impact, vibration, and insulation issues in harsh environments.
• Feed-Through Mounting: Convenient installation thanks to line and load side mounting legs—no extra connectors needed.
• Legacy System Compatibility: Uses the Type NAL frame, making it a drop-in upgrade for older installations without rewiring.

Material Compliance and Certifications

• This breaker is built from high-quality materials that meet industry standards for electrical durability and safety.
• Each unit is factory tested and certified to applicable ANSI/UL/IEC requirements (or equivalent) to ensure reliable performance under demanding conditions.
• All components are selected for long life, insulation integrity, and resistance to thermal stress.

Where It Works Best

• The NAL36800 is ideal for medium to large industrial or commercial distribution systems—think manufacturing plants, data centers, high-rise complexes, or utility substations. Because it's compatible with legacy Type NAL frames, it's beneficial when upgrading older electrical gear without a complete teardown. It excels in applications where a high interrupting rating is essential and where downtime or failure is not acceptable.
