Square D | PHF2036-900A | Circuit Breaker | 900A | 3-Pole | 600V

Meet the Square D PHF2036-900A circuit breaker—a rugged, high-current protective device engineered for demanding three-phase power systems. With a 900A rating, a 3-pole configuration, and a 600V maximum, this breaker is built to safeguard heavy equipment and critical loads in industrial environments while maintaining smooth, reliable distribution.

Key advantages

• 900A rating provides robust protection for high-demand circuits, helping prevent costly downtime from faults and overloads.
• 3-Pole design ensures synchronized tripping across all three phases, preserving balance and reducing the risk of partially energized faults.
• 600V maximum rating makes it suitable for mid- to high- voltage distribution within industrial panels and equipment feeds.
• Designed for maintenance, retrofit, and replacement needs—a practical choice when upgrading aging gear or restoring panel performance.
• Clear part identification (PHF2036-900A) supports accurate ordering and fast procurement, reducing compatibility guesswork.

Ideal use cases

• Maintenance and retrofit projects in industrial facilities where a precise 900A, 3-pole, 600V protection device is required.
• Replacement: swap out failed breakers in Square D panels without altering existing buswork or panel architecture.
• New installation segments that demand reliable three-phase protection for high-current equipment feeds.

Compatibility and ordering tips

Notes: Confirm fit and ratings before ordering. The part number PHF2036-900A is the best reference for compatibility with your Square D installation.
