Square D | NCP36800 | Circuit Breaker | 800A | 3-Pole | 600V

Introducing the Square D NCP36800 Circuit Breaker — a robust, business-ready solution for large-scale electrical systems that demand dependable three-phase protection. Engineered to integrate into maintenance, retrofit, or replacement projects, this 800 A, 3-pole breaker delivers trusted performance in demanding environments while matching Square D's NCP family design language.

Key specifications at a glance:

• Amperage (Current Rating): 800 A — designed to interrupt and limit fault currents in high-load circuits.
• Configuration: 3-Pole — ensures synchronized disconnection across all three phases for reliable three-phase protection.
• Maximum System Voltage: 600 V — suitable for medium- and high-voltage distribution within industrial panels.
• Reference for Compatibility: Part number NCP36800 is the best reference when verifying fit with your equipment.

Why this matters for your operation:

• The NCP36800 is purpose-built for maintenance, retrofit, or replacement projects where an 800 A, 3-pole device is required, helping minimize panel downtime and ensure continuity of service.
• Using the correct part number ensures your breaker mounts correctly, aligns with bus bar configurations, and maintains the protective coordination your system relies on.
• Three-pole protection with a 600 V rating supports high-efficiency motor circuits, feeders, and critical power distribution paths without compromising safety margins.

How to ensure a perfect match

Before ordering, verify that the NCP36800 fits your Square D panel or enclosure by cross-checking the exact part number against your equipment's maintenance records and replacement history. If you manage multiple sites, keep a reference kit with the NCP36800 to streamline future replacements and retrofit planning.

Ideal use scenarios

• Retrofits upgrading legacy systems to meet modern protection standards without changing control schematics.
• Maintenance replacements in industrial facilities where current rating and three-phase protection are non-negotiable.
• New installations that require high current 3-pole protection in 600 V networks.

Practical tips:

• Always power down and lockout-tagout the panel before removing or installing a breaker.
• Consult your electrical code requirements and coordination studies to ensure proper tripping characteristics and selectivity.
• Store spare NCP36800 units in a clean, dry area to protect contact surfaces and maintain reliable performance.
