Square D | PHF2536-1000A | Circuit Breaker | 1000A | 3-Pole | 600V

Square D PHF2536-1000A is a rugged, exact-match circuit breaker designed to protect high-current, 3‑phase power systems. With a 1000 A rating, a 3‑pole configuration, and a 600 V maximum, this device is built for demanding industrial environments and mission-critical retrofit, maintenance, or replacement projects where precise compatibility matters.

• Amperage: 1000 A
• Poles: 3‑Pole
• Voltage rating: 600 V
• Part reference: PHF2536-1000A, designed for reliable fit in Square D panels and systems

Why this model stands out for demanding installations:

• Exact-fit replacement for existing Square D gear requiring a 3‑pole, 1000 A, 600 V circuit protection solution.
• Ideal for maintenance spares, panel retrofits, and capacity upgrades where staying within the same electrical footprint is essential.
• Minimizes downtime by matching the original form factor, terminals, and mounting characteristics to your current infrastructure.

Use cases and preferred applications:

• Industrial power distribution panels where high-current protection is required for motors and heavy machinery.
• Retrofits or replacements in legacy Square D installations to maintain circuit protection consistency.
• Spare parts inventory for service fleets managing large-scale electrical systems in manufacturing, processing, or facilities management.

Ordering and compatibility notes: Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your equipment. When selecting, verify panel model, circuit configuration (3‑pole), and voltage requirement (600 V) to ensure a seamless fit and reliable operation.

Installation and safety considerations: Prepare for a controlled shutdown and follow site safety protocols. Ensure conductors and downstream components are rated for 600 V and that the mounting and terminal interfaces align with your current installation. This breaker is intended to protect high-current, 3‑phase circuits and should be installed by qualified personnel familiar with square-d series protection devices.
