Square D | PHF2536G-1600A | Circuit Breaker | 1600A | 3-Pole | 600V

Meet the Square D PHF2536G-1600A circuit breaker — a robust, industrial-grade protection device designed for demanding 600V electrical systems. With a 1600A rating and a 3-pole configuration, this breaker is built to safeguard large feeders and multi-phase circuits in maintenance, retrofit, and replacement projects.

Why this specific breaker matters

• Exact spec alignment: Amperage, pole count, and voltage are matched for high-current distribution panels, ensuring reliable protection without the guesswork of substitutions.
• Three-pole protection: Simultaneous disconnection across all phases enhances safety and reduces risks during fault conditions in complex installations.
• 600V compatibility: Designed to handle typical industrial and commercial distribution environments where higher voltage performance is required.

Key specifications

• Amperage: 1600A
• Poles: 3-Pole
