Square D NC36700 700A 3-Pole 600 V Circuit Breaker

The Square D NC36700 700A 3-Pole 600 V Circuit Breaker is a high-capacity safety device designed to protect large electrical systems from overloads and short circuits. With a 700 amp current rating, three poles for three-phase protection, and a 600-volt maximum voltage, this breaker is built to handle demanding industrial and commercial environments where reliability matters most.

Key specifications

• Part number: NC36700
• Current rating: 700 A
• Poles: 3 (three-phase protection)
• Voltage rating: 600 V
• Brand: Square D

Why this design stands out

• Robust three-pole configuration provides reliable protection for three-phase machinery and circuits, helping prevent damage from overloads across all phases.
• High-current capability at 700 A makes it ideal for large motors, heavy equipment, and substantial distribution panels where smaller breakers would be insufficient.
• Dependable Square D build quality—a name trusted in electrical protection—delivering consistent performance in demanding environments.
• Clear identification with the NC36700 designation simplifies warranty, maintenance records, and future replacements within compatible Square D installations.

Ideal applications

• Main service disconnects in industrial facilities and large commercial buildings
• Protection for large motors, pumps, and HVAC equipment in three-phase systems
• Feeder protection in switchgear and panelboards that require high-current, three-pole interruption

Practical considerations and usage tips

• Verify that your electrical system and panel are compatible with a 700 A, 3-Pole, 600 V circuit breaker and that NC36700 matches the intended installation.
• Ensure proper clearance and professional installation to maintain safety and reliability in high-current applications.
• Keep records of part numbers and ratings (NC36700, 700 A, 3-Pole, 600 V) for maintenance, replacements, and future upgrades.
