Square D | MAF36800V | Circuit Breaker | 800A | 3-Pole | 36800V

Protect critical power distribution with precision using the Square D MAF36800V circuit breaker. This high-capacity, three-pole device is purpose-built for demanding industrial environments where reliable protection and exact specifications matter for safe, continuous operation.

Key specifications

• Amperage: 800A
• Poles: 3-Pole
• Voltage: 36800V (36.8 kV)
• Compatibility note: Confirm fit and ratings before ordering. The part number MAF36800V is the best reference for compatibility.

Why choose the MAF36800V for your system

• Designed for three-phase power protection in heavy-duty applications, helping to prevent overloads and minimize unplanned downtime.
• Ideal for maintenance, retrofit, and replacement projects where exact specifications must match existing equipment and panels.
• Part-number accuracy matters: referencing MAF36800V ensures you’re selecting the correct unit for your Square D panel and bus configuration.
• Smooth integration with Square D distribution systems supports consistent protection across critical infrastructure.
• Streamlined procurement for upgrading legacy electrical setups without compromising safety or performance.

Practical use cases

• Industrial facilities upgrading 3-phase power distribution in manufacturing lines, processing plants, or large facilities with high-current needs.
• Retrofits to replace aging breakers in existing Square D panels while preserving compatibility with downstream protection schemes.
• Emergency replacements where an exact 800A, 3-pole, 36.8 kV rating is required to maintain system integrity.

Installation and maintenance tips

• Always verify the panel catalog number and bus configuration before purchasing to ensure full compatibility with MAF36800V.
• Keep the part number handy during ordering and service calls to minimize mismatch risk.
• During replacement, inspect adjacent conductors and mounting hardware for wear to maintain optimal protection performance.
