NA36800 - 800 Amp Circuit Breaker

NA36800 - 800 Amp Circuit Breaker

Safeguard your industrial or commercial power systems with the NA36800, a high-capacity 800 A circuit breaker designed for rigorous performance. This molded-case, 3-pole I-Line plug-in breaker combines thermal and magnetic protection to respond quickly to faults and sustained overloads. Thanks to its impressive A.I.C. (Ampere Interrupting Capacity) ratings, it can handle up to 100,000 A at 240 VAC, 50,000 A at 480 VAC, and 25,000 A at 600 VAC—making it a trusted choice for demanding environments where safety, reliability, and uptime matter most.

Key Features and Benefits

• High fault current capacity: With A.I.C. ratings of 100 k at 240 V, 50 k at 480 V, and 25 k at 600 V, this breaker is built to interrupt severe fault currents without damage.
• Plug-in I-Line format: Simplifies installation and replacement in compatible panels, cutting both labor time and system downtime.
• Reliable molded-case construction: Built to endure harsh conditions and protect internal components from environmental stress.
• Thermal-magnetic trip protection: Offers dependable overload protection as well as rapid response to short circuits.
• Space-efficient footprint: At 14.98″ W × 12.12″ L × 8.07″ D, it fits well in compact panels while still delivering large capacity.

These features give you peace of mind that your systems are adequately guarded against faults and overloads.
