Square D PHF2036G Circuit Breaker, 2000A, 3-Pole, 600V

The Square D PHF2036G circuit breaker is built for demanding industrial electrical service, maintenance, and replacement projects. With a 2000 A rating and a 3-pole configuration, it supports robust 3–phase power distribution at up to 600 V. Verify compatibility by the part number PHF2036G and your specific application requirements.

• Heavy-current capability: 2000 A rating designed to protect high-load feeders and main distribution paths in industrial facilities.
• Three-pole design: Provides balanced protection for standard 3‑phase systems, helping reduce phase imbalances and selectivity concerns.
• 600 V voltage rating: Ideal for common industrial distribution networks that operate at or below this voltage threshold.
• Brand reliability: Square D devices are chosen for durability and predictable trip performance in critical environments.
• Compatibility-oriented: Engineered to integrate with compatible Square D panels and typical 3‑phase bus configurations, facilitating smoother replacements and upgrades.

What problems does it solve? When your facility runs high-current equipment or large motors, you need a breaker that can handle sustained loads without nuisance trips, while still providing fast, reliable protection. The PHF2036G delivers that balance for 600 V systems, helping protect transformers, switchgear, and distribution panels from overloads and short circuits.

Who is this ideal for? Maintenance teams, electrical contractors, and facilities managers overseeing industrial plants, manufacturing floors, and heavy mechanical systems that rely on stable 3‑phase power distribution.

How it compares to alternatives Compared to smaller or single- or dual-pole breakers, the PHF2036G offers a dedicated 2000 A capacity in a 3‑pole format, making it suitable for large-scale applications where high-current protection and 3‑phase safety are essential. Always confirm fitment by part number and application requirements to ensure seamless replacement in your existing gear.

Practical tips:

• Before ordering, confirm that your panel and bus arrangement support a 2000 A, 3‑pole, 600 V device.
• Have a licensed electrician verify all electrical codes and clearance, and follow torque specifications for terminal lugs.
• If you’re unsure about compatibility, message us with your application details and we’ll help confirm fitment with PHF2036G.
