Square D | PAF361000 | Circuit Breaker | 1000A | 3-Pole | 600V

Square D PAF361000 Circuit Breaker is a heavy-duty protective device engineered for demanding industrial power distribution. With a 1000A rating, 3-pole configuration, and a 600V operating voltage, this breaker is built to safeguard large three-phase circuits, motor loads, and high-demand feeders in commercial and manufacturing environments.

• Amperage: 1000A — designed to interrupt and protect high-current circuits without compromising system uptime.
• Poles: 3-Pole — ideal for three-phase power distribution, providing balanced protection across all phases.
• Voltage: 600V — suitable for common industrial distribution networks and equipment requiring substantial insulation margins.
• Application: Perfect for maintenance, retrofit, and replacement projects where identical specs are needed to restore or upgrade a panel, MCC, or large-capacity distribution point.
• Compatibility note: The part number is the most reliable reference for compatibility. Confirm fit and ratings before ordering to ensure seamless integration with your Square D panel or enclosure.

This circuit breaker is designed to meet the needs of facilities that rely on robust, dependable protection for heavy loads. It’s well-suited for main-breaker roles in 3-phase service entrances, large motor circuits, and complex distribution schemes where a single, standardized device simplifies maintenance and spare parts inventory.

Why choose this unit? It combines Square D’s established reliability with a straightforward 3-pole, 600V design that aligns with established industrial standards. By using the exact PAF361000 part number as your compatibility reference, you minimize the guesswork during replacements and retrofits, reducing downtime and ensuring consistent protection across your electrical system.

Practical tips for installation and maintenance — verify panel labeling and the existing interrupting rating matches your system, handle the breaker with care to avoid arcing or physical damage, and keep the original packaging until installation is complete. If you’re upgrading or replacing an older unit, plan for a brief shutdown window to safely swap in the 3-pole, 1000A, 600V protection your installation requires.
